What is potential energy?

Back

Potential energy is stored energy based on an object's position or state. It can be gravitational, elastic, or chemical.

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object or system to another, such as heat transfer from a hot object to a cooler one.

What is an example of energy conversion in a roller coaster?

Back

As a roller coaster climbs to the top of a hill, kinetic energy is converted to potential energy. As it descends, potential energy is converted back to kinetic energy.

What type of energy conversion occurs in a hair dryer?

Back

The energy conversion in a hair dryer is from electrical energy to kinetic energy (fan), and then to thermal energy (heat) and sound energy.
