or Negative?
Intro Activity
Start the tennis ball at someone’s face
Let the tennis ball drop (just let go!)
Observe what happens
In your notebooks…
Draw what happened
Where did it have the most potential energy?
Energy due to position
Where did it have the most kinetic energy?
Energy due to motion
Booklet Notes On page 11 of your booklet: “Potential
Energy”
Potential Energy Practice Gravitational potential energy
equation?
Work and Potential Energy Equation?
Potential Energy Practice
A 75kg man is standing on the edge of a
table 1.5m above the ground. What is his
potential energy?
Potential Energy Practice
A girl jumps a vertical distance of 2.3m. At
the top of her jump (when she is at rest
momentarily), her potential energy is
1,590J. What is her mass?
Potential Energy Practice
A 2kg rock is nudged off of a 15m
cliff. After the rock has fallen 4m,
what is the work gravity has done on
the rock?

5 Minute Break
Store
Each ticket will get you a certain amount of a
material
You cannot get multiple of the same materials
Paper is unlimited
Brainstorming Based on the materials you have or will have in
the future Brainstorm 12 different steps:
Must have different causes and effects! Brainstorm 3 simple “Final Tasks” related to your topic
Recall Specifications Only Step 1 has human interaction One object rises to max of 2 feet A different object falls to min of 0 feet 8 Steps minimum. A step: Cause Effect 30 seconds to 5 minutes
