### Graphing Energy Conversions

All Energy is the ability to do work – we just have different clues to keep track of!

• Gravitational PE

• Height above ground

• Elastic PE

• Stretching or Compression

• Chemical PE

• Food (not yet eaten)

• Gasoline (not yet burned)

• Battery (not yet used)

Gravitational PE different clues to keep track of!

Any time an object has height above a reference point.

Can have Kinetic Energy at the same time.

Let’s look at it in action! different clues to keep track of!

PE & KE

Before it drops, 6 meters high different clues to keep track of!

Dropping, at 5 meters different clues to keep track of!

Dropping, at 3 meters different clues to keep track of!

Dropping, at 1 meter different clues to keep track of!

Right before it hits the ground different clues to keep track of!

Practice: different clues to keep track of!Graph the Energy in the Rubber Band at these 3 points in time

• Lamar stretches a rubber band and points it at Ms. Nicholson.

• He lets go and it launches through the air.

• His aim is bad and it misses Ms. Nicholson and falls on the floor. (Graph the energy RIGHT BEFORE it hits the floor!)

His aim is bad and it misses Ms. Nicholson and falls on the floor. (Graph the energy RIGHT BEFORE it hits the floor!)
