What happens when potential energy and kinetic energy of a ball as it rolls down a hill?

Although your question was silent on the matter, we assume that the ball is at rest at the top of the ramp. At that point, it has no kinetic energy, since it's not moving. Its energy is all potential (due to gravity). When you release the ball to roll down the ramp, potential energy is converted to kinetic energy. (Remember, energy can't be created or consumed; it merely changes its form.) You can calculate the ball's potential energy by multiplying its height, h, and its mass, m, by the acceleration of gravity, g. That is, Ep = hmg. Kinetic energy can be calculated by multiplying 0.5 by the object's mass and the square of its velocity, v2. That is, Ek = (1/2)mv2. So, if you equate the two equations (Ep = Ek) you get hmg = (1/2)mv2. That is a powerful formula that allows you to solve for v if you know h and vice versa. If the ball has significant size and mass and it rolls down the ramp the kinetic Energy gets a little more complicated. The (1/2)mv^2 refers to the linear velocity of the center of mass but you should also add to that the rotational energy of the ball about its center of mass. This formula is (1/2)Iw^2; where I is the ball's moment of inertia and w is the balls angular velocity

∙ 13y agoThe potential energy gets less until the ball gets to the bottom of the hill, at which point the potential energy is zero.
The potential energy that is lost, gets converted to Kinetic energy of the ball that goes faster and faster as it gets more and more of the Potential energy.

∙ 10y agoThey are nominally equal, but there's always a bit of kinetic energy missing
at the bottom because of energy lost to friction on the way down.
If the ball was pushed at the top, then the kinetic energy at the bottom
could exceed the potential energy at the top.

∙ 14y agoIt is neither, it is just a ball!
I could have kinetic energy if the ball was moving.
I has potential energy if the ball can "fall" to a lower level.

∙ 9y agoThere is no any potential energy during ascent--that is, there is zero potential energy.

When a ball rolls down a hill what wasted energy conversion occurs?
Potential energy to kinetic energy
What kind of energy is stored in the rubber band on the rolling toy?
That is potential energy, converted to kinetic energy when the toy rolls.
What happens to the potential energy and the energy of a ball as it rolls down a hill from a position of rest at the top of the hill?
The potential energy gets less until the ball gets to the bottom of the hill, at which point the potential energy is zero. The potential energy that is lost, gets converted to Kinetic energy of the ball that goes faster and faster as it gets more and more of the Potential energy.
When a ball rolls down a hill what energy occurs?
The situation is similar as when an object falls. Potential energy is converted to kinetic energy (including rotational energy in this case); part of that kinetic energy is converted to heat energy.
Is rolling down a grassy hill kinetic or potiental?
Any time something falls, rolls, or slides down, gravitational potential energy is converted into kinetic energy.

As a car rolls down a hill where would the motion and gravitational energy be equal?
As a car rolls down a hill, the motion and gravitational potential energy(GPE) will be equal when the kinetic energy is equal to the potential energy.

Which describes the energy conversions used to make a car down the street?
Assuming it just rolls down a slope, without the engines working: gravitational potential energy will be converted to kinetic energy. The kinetic energy will eventually be converted to heat energy.
If marble rolls across the table does it posses potential or kinetic energy?
The equation is K.E. = ½ * mass * velocity2 Kinetic energy is a measure of an object's energy due to the fact that has mass and is moving. So as long as the ball has mass and is moving, it has kinetic energy. Since all tables have friction the marble will slow down as to rolls and lose some KE. Potential Energy = mass * acceleration due to gravity * height. However since the ball is on a table (height), it also has potential energy. If one end of the table is a little higher than the other, it will gain potential energy as it rolls up the little hill, of course as it rolls up that little hill, it will lose the same amount of kinetic energy as the potential energy it gained. This is called "Conservation of Energy".

When an orange rolls off a table its potential energy is converted into what?
The potential energy is progressively changed to kinetic energy as the orange falls. When it hits the ground most of it is converted to heat.
How does a roller coaster convert potential energy to kinetic energy and then back to potential energy again and again?
So the potential energy is the energy in the car at the top of the first slope. It changes into kinetic energy (Speed with mass) as it rolls down the hill. Then the electric motor winds it back up the hill, putting potential energy in the system again.
