Front

Can energy be created or destroyed?

Back

No, energy cannot be created or destroyed; it can only be transformed from one form to another.

Front

What happens to energy when a basketball bounces?

Back

The energy is transformed into other types of energy, such as sound and thermal energy.

Front

What are the two main types of energy?

Back

Kinetic energy (energy of motion) and potential energy (stored energy).

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field.

Front

What is kinetic energy?

Back

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

Front

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

Back

When an electric current flows through a light bulb, electrical energy is transformed into thermal and radiant energy.

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.

Front

What type of energy transformation occurs in a hydroelectric dam?

Back

Mechanical energy from moving water is transformed into electrical energy.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter; it is the total kinetic energy of particles in an object.
