2
ENERGY the ability to do work
3
WORK is done when you use a force to cause motion
4
WORK a force is moved through a distance
5
“CLUES” – Types of Energy
Kinetic Energy Gravitational Potential Energy Elastic Potential Energy Chemical Energy Thermal Energy Electrical Energy Nuclear Energy Radiant Energy
6
Kinetic Energy Energy of motion Examples: KE = ½*M*V2
7
Gravitational Potential Energy
Stored energy that depends on an object’s height Examples: GPE = M*g*H
8
Thermal Energy Energy of heat Examples:
9
Chemical Potential Energy
Stored energy in chemical bonds in compounds When released, energy can do work Examples:
10
Elastic Potential Energy
Stored energy of a compressed or stretched object Examples:
11
Electrical Energy Energy associated with electrical charges Examples:
12
Nuclear Energy Energy stored within nucleus of an atom Examples:
13
Radiant Energy Energy that travels through space in waves
Electromagnetic Spectrum Examples:
14
Sound Form of kinetic energy – movement of energy through
substances in the form of waves
15
