What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a rock at the top of a hill 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 gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground. The higher the object, the more gravitational potential energy it has.

How do plants get their energy?

Back

Plants get their energy from sunlight through a process called photosynthesis.

Front

How do humans get their energy?

Back

Humans get their energy from food, which provides the nutrients needed for our bodies to function.

Front

How do cars get their energy?

Back

Cars get their energy from gasoline, which is burned in the engine to produce motion.

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 an example of energy transformation?

Back

An example of energy transformation is when a battery (chemical energy) powers a flashlight (light energy).

Front

What is solar energy?

Back

Solar energy is the energy we receive from the sun, which can be converted into heat or electricity.
