What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or configuration. It has the potential to be converted into kinetic energy.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy an object possesses because of its height above the ground. It is calculated using the formula: PE = mgh (mass x gravity x height).

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion. It is calculated using the formula: KE = 1/2 mv² (1/2 x mass x velocity squared).

Front

What type of energy does a blimp have while flying?

Back

A blimp has both kinetic energy (due to its motion) and gravitational potential energy (due to its height above the ground).

Front

If an object is at the top of a hill, what type of energy does it have?

Back

It has gravitational potential energy because it is elevated above the ground.

Front

True or False: A rock at the edge of a cliff has kinetic energy because of its position.

Back

False. The rock has gravitational potential energy due to its height, not kinetic energy.

Front

What is Elastic Potential Energy?

Back

Elastic Potential Energy is the energy stored in elastic materials as the result of their stretching or compressing, such as in a compressed spring.

Front

True or False: A compressed spring does not have elastic potential energy.

Back

False. A compressed spring has elastic potential energy due to its deformation.

Front

Which type of potential energy is NOT due to a force field?

Back

Thermal Potential Energy is not due to a force field; it is related to the internal energy of particles.

Front

What is the formula for calculating Gravitational Potential Energy?

Back

PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
