Energy Test Review

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a rock at the top of a hill has potential energy because of its height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What is energy transformation?

Back

Energy transformation is the process of energy changing from one form to another, such as potential energy converting to kinetic energy.

Front

Give an example of energy being converted from potential energy to kinetic energy.

Back

A falling apple is an example of potential energy converting to kinetic energy as it moves downward.

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, like a stretched rubber band.

Front

How does speed affect kinetic energy?

Back

As the speed of an object increases, its kinetic energy also increases.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is an example of kinetic energy in everyday life?

Back

A moving car is an example of kinetic energy, as it is in motion.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy held by an object because of its height above the ground, like a book on a shelf.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.
