What is the law of conservation of energy?

Back

Energy cannot be created or destroyed; it can only be transformed from one form to another.

What is potential energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

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 type of energy transformation occurs in photosynthesis?

Back

Light energy is transformed into chemical energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object.

Front

How does energy transformation occur in a roller coaster?

Back

As the roller coaster goes up, potential energy increases; as it goes down, potential energy is converted to kinetic energy.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter.

Front

What is an example of energy conversion in a light bulb?

Back

Electrical energy is converted into light and thermal energy.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves.
