Examples of elastic potential energy include a rubber band, spring, bouncing ball, catapult, bungee cord, bow string and trampoline. Elastic potential energy is stored in these objects when they are pulled, stretched or compressed. This energy becomes kinetic energy when these objects return to their original shape. For instance, a compressed spring has elastic potential energy until the coils return to their original alignment and push other objects away.Know More
A bow string stretches thanks to the flexibility at both ends of the string. When an archer releases the string, the potential energy releases the arrow, moving the projectile forward. A trampoline stretches as someone jumps on it, and then it returns to its original shape after launching the person into the air. When a rubber ball bounces off a solid object, it loses some of its shape before returning to its original condition in the air. An elastic waistband gets stretched when the clothing is on someone's hips, and then the band returns to its original shape when the clothing is removed.
The more a device stretches, the more elastic potential energy exists. The force that returns an object to its original shape is the restoring force. After an object returns to its original form, it does not contain any potential energy because it reaches equilibrium with its physical surroundings. Anything that is elastic has potential energy until it returns to its original shape.Learn more about Motion & Mechanics
Potential energy that depends on height is called gravitational potential energy. If an object is in a vertical position, then gravity is acting on it as a downward pull. Although the amount of gravitational potential energy an object has depends on the height, the object's mass is another influencing factor.Full Answer >
Gravitational potential energy depends on the mass of the object, acceleration because of gravity and the height of the object from a zero position, which is typically the ground or surface where the object is resting. This is because potential energy is the amount of energy stored in an object due to its position and represents the potential for a force, such as gravity, to do work on the object.Full Answer >
Potential energy is the stored energy of an object that has the potential to change to a different form of energy to do work. The types of potential energy are gravitational, elastic, chemical, electric and nuclear.Full Answer >
Kinetic and potential energy are both typically ascribed as forms of mechanical energy and can be interchangeably converted. Potential energy can be converted into kinetic energy and vice versa, but the change is always accompanied by the dissipation of some energy as heat.Full Answer >
