6.8b Energy Transformation

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as from chemical energy to mechanical 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 potential energy?

Back

Potential energy is the stored energy of 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 mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object that is used to do work.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food or fuel.

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 a substance.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It powers devices like lights and appliances.

Front

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

Back

In a light bulb, electrical energy is transformed into light energy and thermal energy.

Front

What happens to energy in a closed system?

Back

In a closed system, energy cannot be created or destroyed; it can only be transformed from one form to another.

How does a hawk use energy from its food?

Back

A hawk transforms chemical energy from the mouse it eats into mechanical energy to fly.
