Goal 2: Potential and Kinetic Energy

Falling

1

Which position in the diagram would result in the most potential energy for a falling object?

A - Observation Deck

2

Put the levels in order from LEAST potential energy to MOST Potential energy if something were dropped off the Eiffel Tower.   

D, C, B, A

3

Describe how the pie chart would change from the Empire State building to the Eiffel Tower.

1- All blue
2- Smaller

Blob

1

Whose Energy is transferred to the airbag?

David's

2

Describe the change in David's energy as he jumps from the platform.

His potential energy decreases as his Kinetic energy increases

3

How do we know when kinetic energy is being transferred between objects? 

There is a change in motion in both objects.

4

Describe all of the energy transfers happening throughout the picture.

1- David's PE -> KE
2- The blob transfers David's KE into Anna
3- Anna absorbs KE from blob
4- Anna's KE -> PE
*5- Anna's PE -> KE

Graphs

1

If something is dropped from the observation deck, which pie chart most accurately represents the pie chart when that object reaches level C in its fall?

2

2

Which labeled point on the graph represents an object that would cause the most damage to a stationary object?

F

3

What type of relationship exists between mass and kinetic energy?

Proportional*

As mass goes up, the KE goes up. 

4

The Kinetic energy gets two times bigger because the ____________ gets two times bigger.

Mass
