Example: Roller Coaster stuck at the Top of its first hill.
Potential Energy
Mass= 10
Velocity=2
20
a movement of energy or flow of electrons through its path
What is Electrical energy
Geothermal heat is an example of this kinetic energy
What is Thermal Energy?
Describe Elastic PE:

Two forms also known as motion
What is Mechanical and Kinetic Energy?
Name two ways to increase kinetic energy of a roller coaster.
Higher hills; steeper drop; increase mass of cart; velocity, increase the number of carts (any of these count☺)
This type of potential energy is stored in the nucleus of an atom
What is Nuclear?
At which point on a bookshelf would you have the greatest gravitational PE. And why?
The top.
Find the GPE:
Mass=10
Height= 4
40
Energy is neither created nor destroyed
What determines kinetic energy
What is the velocity of the object
What are the two types of Potential Energy?
1. Elastic
2. Gravitational
Where is the point of greatest kinetic energy?
PE is the lowest.
Find Height given the following:
Mass: 20
GPE: 100
