Energy and Transformations

Front

What is energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It increases with the speed of the object.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a roller coaster at the top of a hill has potential 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 from one form to another.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It is commonly used to power devices like lamps and appliances.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food and fuels. It is released during chemical reactions.

Front

How does energy transform in a lamp?

Back

In a lamp, electrical energy is transformed into light energy when the lamp is functioning.

Front

What happens to kinetic energy as an object speeds up?

Back

As an object speeds up, its kinetic energy increases.

Front

What type of energy is found in food?

Back

Food contains chemical energy, which is released when the body metabolizes it.

Front

What type of energy does a moving roller coaster have?

Back

A moving roller coaster has kinetic energy.
