8
Our Energy Skate Park assignment explores a few things:
The relationship between Kinetic, Potential, and Thermal energy
How mass influences speed
How friction influences energy levels
9
How to increase potential energy
There are 2 ways to increase the potential energy of an object in relation to gravity.
-Increase the object's height.
-Increase the object's mass.
10
Poll
Which has the most potential energy?
A
B
C
D
11
Kinetic Energy
The amount of Kinetic energy an object has is related to to 2 factors.
- Mass of the object
- Speed of the object
12
Multiple Select
If a football player wants to become better at tackling by increasing their kinetic energy, how can the player do this?
Increasing their height
Decreasing their speed
Increasing their mass
Increasing their speed
13
Potential and Kinetic Energy
Notice that as the kinetic energy increases the potential energy decrease.
When the coaster goes back up the hill the energy is converted back to potential energy.

Type answer...
15
Total Energy
the sum of all energy in a system
kinetic + potential + thermal = total energy
16
Open Ended
The Law of Conservation of Energy states "Energy is not created or destroyed, only changed." How does the relationship between potential, kinetic, and thermal energy in this image illustrate this?
17
Friction:
The resistance to motion of one object moving relative to another
