Types of Energy
2
What is energy?

• Its the ability to do work or cause change.
• Its measured in Joules (J).
• Joules measures work and energy.

3
What is kinetic energy?

• Its the energy of motion.
• Kinetic energy mass x velocity2
• 2

4
What is potential energy?

• Its stored energy the ability to do work but
  not doing it yet.
• 2 types
• elastic and gravitational

5
What is elastic potential energy?

• Its energy of objects that can be stretched or
  compressed.
• Ex bungee cord, Laffy Taffy, bread, spring,
  balloon

6
What is gravitational potential energy?

• Its energy that depends on height.
• GPE weight x height
• GPE x
  x

Acceleration due to gravity
mass

9.8 m/s2
7
What is mechanical energy?

• Its energy associated with a change in motion or
  position. It can be kinetic or potential.
• Ex Walking, frog, machine

8
What is chemical energy?

• Its energy thats stored in chemical bonds.
  Its a type of potential energy.
• Ex chocolate, wood, wax, body cells, food

9
What is electrical energy?

• Its energy from electric charges that are moving
  to produce electricity.
• Ex static electricity, lights

10
What is electromagnetic energy?

• Its energy that travels in waves. It has
  electrical and magnetic properties.
• Ex visible light, UV, infrared, microwaves

11
What is nuclear energy?

• Its energy stored in the nucleus of an atom and
  released during a nuclear reaction.
• Atom splitting
• Atom joining
• Ex atom bomb, the sun, nuclear power plant
