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

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
