Answer:
The first hill of a roller coaster is always the highest point of the roller coaster because friction and drag immediately begin robbing the car of energy. At the top of the first hill, a car's energy is almost entirely gravitational potential energy (because its velocity is zero or almost zero
Explanation:
yes, because the Hight provides it with enough energy so it makes it to the end of the ride.
Explanation:
ok lets see there is a cart on top of a small hill and there is another cart on top of a bigger hill. they Hight of the bigger hill will give the cart time to pick up more speed then the other crat why because of they Hight and yes gravity has to d with it the higher you are the more the gravity will try to pull you down. so the gravity will pull the crat in the higher hill down faster
