What else can I help you with?
What type of energy exists in a ball sitting on top of a hill?
kinetic energy
What are the two main forms of energy?
The two main forms of energy are Kinetic energy and Potential Energy. Kinetic energy is motion energy. Potential energy is energy stored in matter.
What uses kinetic energy from moving air?
the brakes on a bicycle when used turn kinetic energy into chemical energy.
Explain how the motion of a swing illustrates the transformation between potential and kinetic energy?
1) at the top of the swing, the swinging object has all potential energy and no kinetic energy (no speed at that moment) while at the bottom there is no potential energy but a maximum in kinetic energy, so that the swinging object is fastest at the bottom.
How is energy transferred during a pendulum swing?
A swinging pendulum has potential energy at each end of it's travel (when it stops momentarily) This energy is converted to kinetic energy as it swings down and back to potential energy as it swings up the other way.
What form of energy does a bicycle coasting along a flat road best demonstrate?
Conservation of momentum.
Is coasting downhill on a bike a chemical energy?
No, it's potential energy turning into kinetic energy.
How does the energy associated with a bicycle change as it speeds up going downhill?
The energy associated with a bicycle changes as it speeds up going downhill due to the fact that potential energy is converted to kinetic energy. The potential energy is the energy of the position. The kinetic energy is the energy of movement.
How a bicycle kinetic energy changes when that bicycle slows down?
As a bicycle slows down, its kinetic energy decreases. This is because kinetic energy is directly proportional to an object's velocity squared, so as the bike's speed decreases, so does its kinetic energy. The energy is either dissipated as heat due to friction from the brakes, or stored temporarily as potential energy if the bicycle is going uphill.
What forms of energy are involved in a bicycle coasting along a level road?
It's probably a bit of both. As long as the bike is moving it'll have some kinetic energy. If it's moving uphill it'll be gaining potential energy and if it's moving downhill it'll be losing potential energy.
What happens to the kinetic energy of a skateboard that is coasting along a flat surface slows down and coming to a stop?
it change into potential energy beace it slows down
Does a stationary bicycle have kinetic energy?
Yes, a stationary bicycle has kinetic energy when the rider pedals, as the rotational motion of the pedals and wheels generates kinetic energy. However, since the bike is stationary, this energy is not being used to move the bike forward.
Energy stored in a bicycle at the top of a hill?
The energy stored in a bicycle at the top of a hill is potential energy, which is due to its position relative to the ground. This potential energy can be converted into kinetic energy as the bike descends the hill and gains speed.
A boy on a bicycle is resting at the top of a hill. Then, he rides his bicycle down the hill. Describe how the boy’s potential and kinetic energy differ at the top, middle, and bottom of the hill.?
At the top of the hill, the boy has high potential energy due to his elevated position. As he rides down, his potential energy decreases and his kinetic energy increases, reaching its maximum at the bottom of the hill. At the bottom, his potential energy is low, while his kinetic energy, which is the energy of motion, is highest.
Is hydroelectric tidals potential or kinetic?
kinetic
What store of energy does a bicycle carry?
A bicycle carries kinetic energy when it is in motion. The kinetic energy comes from the rider's pedaling efforts and is stored in the motion of the bicycle and rider.
Does a moving bicycle have kinetic energy?
Yes, a moving bicycle has kinetic energy. Kinetic energy is the energy possessed by an object due to its motion. As the bicycle moves, it possesses kinetic energy that is dependent on its mass and velocity.
