What goes up and down a hill without moving

I tried using conservation of energy to find the height Looking at the question logically rather than academically; wouldn't you need the slope of the hill to calculate the distance traveled.

Discounting friction wouldn't the ball decelerate going up the hill at the rate of gravity acceleration. Quantifying the deceleration over the time required to transverse the hill would give the forward velocity as it left the cliff. Vertical velocity would be the acceleration of gravity achieved in 28m.

The time required to impact the ground would provide the distance traveled from the cliff face based on the forward speed. A bullet fired horizontally falls at the acceleration of gravity regardless of it's forward speed. Just a thought and I don't mind being wrong but I would be interested in the correct theory of the calculation. You must mean that the ball moves horizontally at the top of the hill until it reaches the cliff.

The initial kinetic energy of the rolling ball is. Going up the hill, the remaining kinetic energy is 0. Trending News. A warning sign for Trump at The Villages in Florida.

Get your answers by asking now.You need to have enough power to be able to accelerate a vehicle anywhere, especially up a hill where gravity is pulling against it.

If there are any faulty components in the vehicle, then this could make it harder for the engine to push the vehicle up the hill as you attempt to accelerate. There are so many reasons for why this could happen, so you need to pay attention to the various causes and possibilities for this.

Fuel filters typically have a service interval for when they must be changed. If the fuel filter is not changed for a long time, eventually the particles and sediment from the gas tank will build up and clog the filter, restricting fuel flow. If the flow of fuel is restricted too much, not enough will be able to reach the fuel injectors and the car is likely to run lean.

The catalytic converter and the muffler serve as filters for the exhaust pipe, for harmful emissions and sound respectively. The muffler reduces the noise from the exhaust and the catalytic converter reduces the exhaust pollution. A clogged exhaust can be dangerous, as it is a fire hazard in extreme cases. If you think your exhaust may be clogged, the issue should be addressed as soon as possible. As much as the internal combustion chamber needs clean fuel, it also needs clean air to be mixed together with it to keep the engine powerful.

It is important to have a clean air filter that is not clogged so air can continue to pass through the filter and enter the chamber without the impurities in it. Otherwise, the engine will never be powerful enough to make it up a hill. Vacuum leaks often only affect vehicles at idle, but if the leak is bad enough it may affect overall vehicle performance. A vacuum leak can be tested for using a smoke test to make sure the air intake system is sealed tight like it should be.

A vacuum leak will make the vehicle run lean as unmetered air is enters the intake manifold. Fuel injectors are the last parts before the combustion chamber in a long list of components that make up the fuel system.

Injectors usually last for a long time, but they can become clogged with age or poor fuel quality as the fuel filter fails to pick up all the sediment from the gas tank. If the injector clogs completely or stops working, no fuel will reach the combustion chamber and no power will be made on that combustion stroke. If the fuel pump is on its way outit may work intermittently or not at all. A symptom of starving the car for fuel is a car that runs correctly at idle and low load, but falls flat on its face as you ask for more power when climbing a hill, for instance.

Fuel pumps may fail due to age, sediment buildup, or running the incorrect fuel. If you drive around with a nearly empty gas tank often, you may want to rethink that habit. Fuel is used to cool the fuel pump, and running with less than a quarter tank for long periods of time may reduce the life of the fuel pump substantially.

As your spark plugs age, the spark gap can increase as the center and ground electrode s wear out. If this gap becomes too great, the spark may not always be able to jump the gap. No spark means no combustion in that cylinder, which leads to misfires. This is a wasted combustion cycle where no power is generated. Ignition coils and spark plug wires convert the low voltage power from the battery into the high voltage necessary to jump the spark plug gap. As ignition coils and wires wearthey may lose insulation and short out.

When this happens, sufficient voltage may be unable to reach the spark plugs, causing misfires. The camshaft position sensor calculates the camshaft speed and transmits this information to the electronic control module. That way, the engine control module can manage the ignition timing and fuel injection timing properly. But if you were to have a faulty camshaft position sensorthen the timing on these two would be off.

Having high cylinder compression is critical for giving the engine enough power to get the vehicle up a hill.Last Updated: September 3, References Approved.

Typically, automatic transmission cars don't easily roll back. If they do roll, it's usually a little; not all the way down the hill. However, if you're concerned your car will roll, you can use your handbrake.

To prevent a car with manual transmission from rolling back on a hill, come to a complete stop and engage the handbrake. Next, shift into first gear and step on the accelerator pedal until the engine spins at about RPM.

Then, lift the clutch and slowly release the handbrake so that the car begins moving forward slowly. When the sounds of the engine start to fade, continue applying throttle and drive the car up the hill. For tips on preventing roll-back in a vehicle with automatic transmission, read on!

Moving 40 yds of sand down a large steep hill. Thread starter SpartanBill Start date Aug 8, SpartanBill LawnSite Member. We have a project coming up installing 40 yds of beach sand at a lake res. It's about 50 vertical feet at about 1. We're figuring on building a chute OSB and 2x4swheel barrowing to, dumping into, and possible dragging along and loading wheel barrows at the bottom.

Any one do a project like this? Ideas, suggestions, thoughts? Thanks, Bill. F4rm3rj03 LawnSite Senior Member. Location Winfield, Missouri.

Shifting to a lower gear is the key to delivering power to your wheels and controlling your speed. Even if you drive an automatic, manually downshifting is wise when driving both uphill and downhill. In addition to mastering downshifting, you should also work on parking and starting techniques. It might take a little practice, but you can get the hang of driving uphill in no time!

Safety tip: Keep in mind the posted speed limit may be too fast if the road is slick. For instance, the posted limit may be 65 mph about kphbut you should drive half that speed or less in bad weather. Tip: Gear markings vary by make and model. Check the gear stick the stick that you move from park to drive for markings such as D, D1, and D2. In residential or urban areas, for instance, you may need to avoid pedestrians or cyclists. If there's no curb: Whether your vehicle faces uphill or downhill, park with the wheels turned sharply away from the street.

Tip: If the car grumbles or strains, depress the clutch just a bit. Depressing the clutch all the way can make you miss the biting point. You should be able to release the parking brake, keep the foot brake depressed, then hit the gas pedal without rolling backward. To drive uphill with an automatic transmission, start speeding up as you approach the hill so you gain some momentum. Your automatic transmission should downshift for you once you start driving uphill, but if you're driving up a particularly steep slope or driving a heavy vehicle, you may want to downshift to the gear range marked D2, 2, or L.

For even steeper hills where you can't exceed 10 miles per hour, downshift to the lowest gear, which is usually D1 or 1. To learn how to drive uphill with a manual transmission, read on! Did this summary help you?

When I jumped it I instantly viewed arcing off the ground connection at the frame, with about 5 wires junctioning together.

I'm going to pull the battery out tonight and charge the battery, then take it over in the morning and get it tested to see if the battery is bad, something else.

I'm getting prices ranging up and down on this centrifugal clutch Anyone know if this is a common failure part on these? I still haven't found any online parts diagram of my 2 cycle motor to know more about the mechanics of the cart. Video of how this golf cart runs. First check your engine compression. I would bet that your clutches and belts are shot. Find More Posts by mikesmotortoys. That cart is a lot like mine!

On the passenger side by your feet there is a tag with two sets of numbers on it. Mine is an 84 I think it is the bottom set of numbers on the tag.

Hope this helps. Thanks for the responses. This golf cart caught on fire thursday night. It has too large a battery in it and the positive lead hit the front wall of the cart and burned the connection right off, along with some toxic foam. Didn't get a chance to do either but it's been running all day in a subdivision going up and down hills. As long as it stays on flat ground, it works out great but the first incline and it lets you know.

It's next on the list, now that I have the exterior done. Can you do me a favor and measure the distance from the floor to bottom of the roof? I am going to make a roof and just need to know that distance as a reference point for the rest of the build.

One thing I can tell you is DON"T slam from fwd to rev like that. A 2 stroke actually runs the engine in reverse direction to go in rev. If you keep doing that, your going to break a rod. I would still check compression in both fwd and rev. It should be minimum. It doesn't sound like yours is taching up. Also, check drive belt. Is it worn? Is it slipping when your moving up hill on the driven pulley?

What is the the drive pulley doing when your moving up hill?When Sir Isaac Newton first felt an apple bounce on his head, the theory of roller coaster movement was born.

A roller coaster moves in the same way a marble would roll down a slanted surface. The marble rolls because it has Gravitational Potential Energy. Potential Energy is gathered by an object as it moves upwards, or away from, the Earth. A roller coaster train gains potential energy as it is pulled up the lift hill to its highest point; the train gains more potential energy the higher it goes. When an object falls back to Earth, it gathers Kinetic Energy. A transfer of Potential Energy to Kinetic Energy occurs when the roller coaster train leaves the top of the lift hill and powers down the first drop.

The greater the potential energy in the train gathered during the lift hill climb, the more kinetic energy the train will have at the bottom of the drop. All objects falling to the ground seek the fastest way down which is typically straight down. The roller coaster rails control the angle of descent meaning the steeper the first drop, the greater the kinetic energy.

The kinetic energy at the bottom of the drop determines how far the coaster train can travel along the track and through inversions, banked turns and airtime hills. The calculation between the lift hill and the drop heights have to be precise, otherwise the train will not gather enough potential and kinetic energy to complete the circuit.

Coaster designers then have to consider what happens after the first drop. If the track after the first drop was completely flat and straight, the kinetic energy would, theoretically, allow the train to continue moving forever, as energy does not disappear. However, in the real world, forces such air resistance and friction between the wheels and the track dissipate the kinetic energy.

Train will stop moving without kinetic energy. And it would be a very boring roller coaster! This would be another dull coaster, but this would make the news as it is destined to get stuck. In this situation, when the train accelerates down the first drop and climbs up the second element, it would roll back. Even though, theoretically, the train has the kinetic energy to get up the same size hill as the first drop, some kinetic energy would be lost yet again due to friction and air resistance.

Providing the element after the first drop is low enough to take the weight of the train into consideration, this is the perfect situation allowing the coaster to continue to the next element. Several forces are felt when riding a roller coaster, and keeping these within safe values is a vital skill for roller coaster designers. G stands for Gravity and the number in front of it represents how many times the force of gravity is felt at a particular point.

Everybody experiences 1G in everyday life, the regular force of gravity when still. If a theme park says a roller coaster rider will experience, for example, 4G, the rider will briefly experience four times the force of gravity.

In simpler terms, if a rider person weighs kg while standing still, they would momentarily weigh kg at the 4G point of the ride. G Forces create the airtime that riders experience. Ejector Airtime is where the rider feels they are being quickly ejected from the coaster.

Floater Airtime is a smoother sensation where the rider feels they are weightless. Positive G-Force occurs at the bottom of a drop when the train wants to continue moving in the same direction, but the track forces it in a different direction.

The sharpness of this change of direction determines the positive G.
