Energy Review

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

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

Front

What happens to kinetic energy when friction increases?

Back

The kinetic energy decreases because friction slows down the object.

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy is never created or destroyed, only transferred.

Front

What type of energy is stored in food?

Back

Chemical energy.

Front

What is an example of energy transfer when using a stove?

Back

Thermal energy from the stove is transferred to the food, which is then used as chemical energy by our bodies.

Front

What type of energy does gasoline represent?

Back

Gasoline is a form of chemical energy.

Front

What is mechanical energy?

Back

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

Front

What type of energy transfer occurs in a windmill?

Back

Mechanical energy is converted to electrical energy.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces in contact.
