Energy Transformations

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a swing at the highest point has potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting chemical energy in food to kinetic energy when we move.

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 type of energy is electrical energy in motion?

Back

Electrical energy in motion is called kinetic electrical energy.

Front

What energy transformation occurs in a battery-operated device?

Back

In a battery-operated device, chemical energy is transformed into electrical energy, which is then transformed into other forms of energy, such as sound.

Front

What type of energy does a microwave oven primarily transform?

Back

A microwave oven primarily transforms electrical energy into thermal energy (heat) and light.

Front

What is an example of potential energy?

Back

An example of potential energy is a book on a shelf. It has potential energy due to its height above the ground.

Front

What is an example of kinetic energy?

Back

An example of kinetic energy is a rolling ball. It has kinetic energy because it is in motion.

Front

What happens to energy during a transformation?

Back

During a transformation, energy changes from one form to another, but the total amount of energy remains constant.
