Gathering class data First four to finish quiz get data Fifth student in charge of answers for workbook
Activity Two Affect of change in mass with acceleration of cart
Sample Data for change in height and cart from block 1
· Change in height
Height distance 1 meter time
8 2.78 sec 2.63 sec 2.55 sec
14 1.64 sec 1.56 sec 1.63 sec
19 1.45 sec 1.33 sec 1.31 sec · Change in mass
200 grams distance 1 meter time
50 grams
25 grams
Challenge Challenge One
1. Calculate avg velocity for change in height data.
2. Plot three lines showing change in velocity for each height.
3. Calculate the slope of each line
Challenge Two
1. Plot three lines for each change in mass.
2. Calculate the slop of each line
Plot data on a line and how to do found in text on page 394

Number Two 
Demo with Computer Simulation phet (Skate Park)
https://phet.colorado.edu/sims/html/energyskateparkbasics/latest/energyskateparkbasics_en.html
Notice what happens to change in a) speed b) potential and kinetic energy when you change the a) height of the skater b) mass of the skater


Topic
Number Three 
Using the skate boarder demo and your data from both cart demonstrations, answer these questions on a separate piece of paper.
1) With the cart, what is the affect of change in acceleration with a change in height?
2) With a skater, what is the affect of change in acceleration with height?
3) What is the affect of mass on the acceleration of the cart?
4) What is the affect of the change with mass on the skater?
5) Is there a difference in between affect of height between the cart and the skater?
6) Is there a difference in between the affect of mass of the cart and the skater?
7) Propose a hypothesis for the cart regarding affect of height and mass for the cart.
8) Propose a hypothesis for the skater regarding affect of height and mass for the skater?
9) If there are differences in the affect of gravity upon the cart and the skater?
10) Can you explain your answer for question number nine, in regards to rules or laws of physics?

Take Home Message  · Motion is affected by a variety of variables.
· Resistance to motion is Inertia · Force = mass times acceleration · For every force there is another equal and opposite force. · Yoda says “Do or Do not, there is no try” so do your homework! · The force is strong in most Jedi Warriors
