- Energy has a number of different forms, all of which measure the ability
of an object to do work on or change another object.
- In other words, there are different ways that an object can possess
energy.

- Kinetic Energy
- Potential Energy
- Thermal, or heat energy

- Electrical Energy
- Electrochemical Energy
- Electromagnetic Energy (light)
- Sound Energy

- Potential energy is energy due to position or stored energy. Potential
energy is also called gravitational potential energy.

- By stretching a rubber band, you give it potential energy. A vase on a
shelf has stored potential energy. A football being held by a
quarterback has potential energy until it is thrown and it turns into
kinetic energy.

- Kinetic energy is the energy of motion. Kinetic energy is measured by
how much is work done to put an object in motion or to rest.

- A basketball player has kinetic energy. The movements that she does show
the energy that is being displayed while she is moving. When you are
running, walking, or jumping, your body is exhibiting kinetic energy.

|
- A waterfall has both kinetic and potential energy. The water at the top
of the waterfall has stored potential energy. Once the water leaves the
top of the waterfall, the potential energy is changed into kinetic
energy.

- Energy cannot be created or destroyed; it can only be changed from one
of form of energy to another form.
- The amount of energy stays the
same.
