What type of energy is a rolling ball?

Answer 1

Well, right before you are about to push it or while it is sitting at the top of a hill, the ball has potential energy. This means the ball has to potential to move or roll. This can be seen as a roller coaster at the tallest point of the ride. Then, while it begins to roll, the ball has kinetic energy while it moves until the forces of gravity and friction are able to stop its kinetic energy.

Answer 2

A rolling ball would have only kinetic energy. Kinetic energy is energy from motion. So if you have something consistently pushing the ball which is causing it to roll then you have two energies; kinetic and the potential energy from that other force. If the ball is rolling on its own already then you only have kinetic energy. Gravitational energy would not be significant in either case because the ball is not rising or dropping. If the ball was falling then it would be losing gravitational energy and gaining kinetic energy (kinetic energy= 1/2mv^2). So since it is falling then the velocity of the ball is increasing and there for the kinetic energy is increasing until it hits a stop. If the ball is bring thrown up into the air then it is gaining gravitational energy because the acceleration (a= velocity/time and v= change is position/change in time) is getting smaller which is making the amount of kinetic energy less. Acceleration increasing as the ball is falling and decreases if the ball is thrown into the air. So since the ball is neither rising nor falling gravitational energy doesn't affect the ball.

Answer 3

A rolling wheel would have only kinetic energy. Kinetic energy is energy from motion. So if you have something consistently pushing the wheel which is causing it to roll then you have two energies; kinetic and the potential energy from that other force. If the wheel is rolling on its own already then you only have kinetic energy. Gravitational energy would not be significant in either case because the wheel is not rising or dropping. If the wheel was falling then it would be losing gravitational energy and gaining kinetic energy (kinetic energy= 1/2mv^2). So since it is falling then the velocity of the wheel is increasing and there for the kinetic energy is increasing until it hits a stop. If the wheel is bring thrown up into the air then it is gaining gravitational energy because the acceleration (a= velocity/time and v= change is position/change in time) is getting smaller which is making the amount of kinetic energy less. Acceleration increasing as the wheel is falling and decreases if the ball is thrown into the air. So since the wheel is neither rising nor falling gravitational energy doesn't affect the wheel.

Answer 4

Kinetic energy refers to the energy of motion. If a ball is rolling, it may roll quickly or slowly (depending on the surface); the faster it rolls, as its velocity increases, so does its kinetic energy.

Answer 5

This would be kinetic energy. It helps the ball to keep moving down the ramp despite all of the other forces trying to stop it.

Answer 6

the energy in a moving ball is kinetic energy then potential energy because when the ball is moving it has kinetic energy and it has to stop...so when it stop, it has potential energy.

Answer 7

A moving ball possesses kinetic energy.

Answer 8

Kinetic energy.

Answer 9

Kinetic.
