Presentation transcript:

Can be stored and moved from one location to another. Energy Notes Can be stored and moved from one location to another.

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.

Energy storage All energy is the same Energy is stored in different ways Analogy: information Analogy: Money

Energy Transfer Energy can move (or flow) from one system to another in different ways Energy transfer changes both systems. Analogy: Information Analogy: money

It’s all the same “stuff” The energy is the same before, during and after the move. Analogy: Information Analogy: money

Gravitational Energy Eg Stored energy Based on an objects position in the gravitational field and its mass.

Gravitational Energy Eg Relationship between mass and Eg Relationship between position/height and Eg.

Elastic Energy Es Stored energy Result of changing an elastic object such as a rubber band or spring.

Kinetic energy Ek Stored energy When things are in motion Affected by mass and speed.

Kinetic Energy Ek Relationship between mass and Ek Relationship between velocity and Ek

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.
