What is electrical energy?

Back

Electrical energy is a type of kinetic energy caused by moving electric charges.

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.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object, representing the total energy of motion and position.

What is the relationship between height and gravitational potential energy?

Back

The higher an object is positioned, the greater its gravitational potential energy due to increased height in a gravitational field.
