Name Here
Motion pg 38-39
• 1. Explain how you know an object is in
motion(38)
• 2.What are two ways to describe motion?
(39)
• 3. What is distance?
• 4. What is displacement?
• 5. How is displacement different than
distance?
• 6. Use Figure 2… what is the distance
traveled by the person… what is the
displacement?
7. Provide a
picture that
represents
distance and
displacement and
explain why
Click Me
• Explain why displacement was zero and
distance was 30 M
Speed(39-40)
• 1. What is speed?
• 2. What is the formula
to calculate speed?
• 3. If a car is moves 100
meters in 10 seconds…
what is the cars speed?
• How is instantaneous
speed different than
average speed?
Use Buttons to make
the speed formula

Go to the following website address:
http://phet.colorado.edu/simulations/sims.php?sim=The_Moving_Man
2) Click the green Run Now! Box. It may take a while for it to load. It may also ask
you to update or install the latest version of Java. Go ahead and do this if you
know how otherwise ask your teacher for help.
3) Once it loads, use the mouse to slowly drag the man to the right as smoothly as
you can until he reaches the wall. Then stop for a few seconds. Next, quickly drag
him to the left all the way to the other wall as smoothly as possible. Stop there for
a few seconds. Finally drag him slowly back to the center as smoothly as possible.
Stop there and then click on one of the little STOP icons.
4) You can repeat this a few times until you get the graphs as smooth as possible.
Use one of the CLEAR icons to erase the graphs and re-center the man.
(5)Graph screenshots
•
Once you have a set of graphs that are as smooth as you think you can get them, screenshot each of following
types …position vs time,
Position Vs. time
1. Pull the man all the way to the left
2. Drag the man to right as fast as you can…
3. when you get half way stop him
4. Take a screenshot of the position vs. time graph
Questions:
What did the graph do when you were going right
What did the graph do when you were going left
What did the graph do when you weren’t moving
