What is a gravity hill?
Seen in the video above, gravity hills (also known as magnetic hills) are a phenomenon that occurs when a false horizon creates the illusion of moving against gravity.
If you drive over a gravity hill, you might feel like you're headed uphill, but if you let off of the gas pedal, you'll keep accelerating. Obviously, that makes for a fairly confusing experience; vehicles might seem to defy gravity, and on rainy days, water seems to rush back up the hill.
There are hundreds of gravity hills throughout the world. Prominent examples in the United States include Spook Hill (Fort Gaines, Florida), the Oregon Vortex (Gold Hill, Oregon), Mystery Hill (Boone, North Carolina), and our favorite, Booger Mountain (Cumming, Georgia).
As these colorful names imply, some people believe that gravity hills occur due to strange magnetic imbalances or supernatural influences. In reality, though, the phenomenon is fairly easy to explain: When traveling on the hill, you're actually on a slight downward slope, but the surrounding landscape gives the impression that you're traveling uphill. You can't see the horizon, so your brain infers that it's behind the "peak" of the hill.
The effect becomes more pronounced when other landscaping oddities come into play. For instance, if the trees surrounding the hill grow at a slight angle, they may appear to be perfectly straight, and drivers will have an even tougher time determining the slope of the land.
Essentially, humans need a clear view of the horizon in order to determine whether they're moving up or down. When the horizon is obstructed, we have trouble judging the slope of a surface. The effect even works if you know that you're being tricked--you'll still feel like you're defying gravity.
Gravity on a plane is less then on a hill because you are away from the earth, However gravity in a plane over a hill is more then gravity on a plane over a valley at the same altitude above sea level. Read More

yes. Going downhill, the gravity is pushing on your forcing you to go downwards. Read More
Why does the force of gravity do work on a car that rolls down a hill but no work when it rolls along a level part of the road?
on earth... as you get closer to the earths core the gravity becomes stronger.. therefore the bottom of the hill being closer to the core the gravity is stronger then the more distant top of the hill. as for the smooth road the gravity is pulling equally on all sides of the car so it cancels its self out and results in u not moving Read More

Rocks fall because of gravity. Gravity is the force that brings things back to earth. Rocks on a slope, mountain, hill, etc. fall or roll down the hill with gravity. Also, mudslides and other things can push rocks down. Read More

friction and gravity affect snow skiing because skiing uses sliding friction which rubs against the snow to make it slippery. friction also affects skiing because it allows you to go up hill. gravity keeps you down and able to go down a hill. gravity also affects skiing because it makes it harder to go uphill.

It pulls you down, making your job much easier because that causes you to move downhill since the bottom of the hill is closer to the center of the earth than the top of the hill. Read More
