What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, including kinetic, potential, thermal, electrical, chemical, and radiant.

Front

What type of energy is associated with motion?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What type of energy is stored in an object due to its position?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What is an example of energy transformation?

Back

An example of energy transformation is a wind turbine converting kinetic energy from wind into electrical energy.

Front

What device converts electrical energy into light and sound energy?

Back

An alarm clock converts electrical energy into light and sound energy.

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, such as light.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, related to the motion of particles.

Front

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.

Front

What is an example of potential energy?

Back

A picture hanging on the wall has potential energy due to its position.

Front

What happens to energy when a ball rolls down a ramp?

Back

The potential energy of the ball is transformed into kinetic energy as it rolls down the ramp.
