ENERGY The ability to do work &/or cause change Examples:
It’s best to think of it like “stuff” that you can store & move in different ways.
3
Energy storage All energy is the same
Energy is stored in different ways Analogy: information Analogy: Money
4
Energy Transfer Energy can move (or flow) from one system to another in different ways Energy transfer changes both systems. Analogy: Information Analogy: money
5
It’s all the same “stuff”
The energy is the same before, during and after the move. Analogy: Information Analogy: money
6
Gravitational Energy Eg
Stored energy Based on an objects position in the gravitational field and its mass.
7
Gravitational Energy Eg
Relationship between mass and Eg Relationship between position/height and Eg.
8
Elastic Energy Es Stored energy
Result of changing an elastic object such as a rubber band or spring.
9
Kinetic energy Ek Stored energy When things are in motion
Affected by mass and speed.
10
Kinetic Energy Ek Relationship between mass and Ek
Relationship between velocity and Ek
11
Law of Conservation of Energy
When energy moves from one location to another, the total amount of energy stays the same. Energy is not created or destroyed but can be transferred between objects.
