# Potential and Kinetic Energy Power Point

```Potential &amp; Kinetic
Energy
Energy
• The ability to do work
• The ability to cause matter to move
• The ability to cause matter to
change
• Measured in joules &amp; calories
Types of Energy
•
•
•
•
•
•
Nuclear (atomic)
Mechanical
Heat (thermal)
Sound
Chemical
You will see other types or forms of energy in
books and on the Internet
Energy can be divided into
two general categories:
• Potential
• Kinetic
Potential Energy
• Stored energy
• Energy of position
• The amount of usable energy in a body at
rest
• Sometimes called GRAVITATIONAL
POTENTIAL ENERGY
Potential Energy
• Can be calculated mathematically
• PE = (weight) (height)
Potential energy can be
increased by:
• Increasing height
• Increasing mass
Example
Kinetic Energy
• Energy of motion
• Energy an object has because it is moving
Kinetic Energy
• Can be calculated mathematically
• KE = (mass x velocity2)/2
Kinetic energy can be increased
by:
• Increasing mass
• Increasing speed
