Note: This week you will need a stopwatch. This can be either your phone, a physical stopwatch, or an online one. If you need an online one, simply Google "stopwatch" as Google has one built in to its site.
- Select the tab labelled "Motion."
- Play around with the simulation to get familiar with it.
- Investigate and click around making sure you try everything out.
- Reset via the yellow reset button on the right side of the screen.
- Turn on "Speed."
- At the same time, start your stopwatch and press the +50N button once.
- Stop your stopwatch when the speedometer maxes out.
- Question 1: Describe the motion of the crate on the skateboard.
- Question 2: How long did it take to reach maximum speed?
- Reset, and turn "Speed" back on.
- At the same time, start your stopwatch and press the +50N button twice.
- Stop your stopwatch when the speedometer maxes out.
- Question 3: Compare the observed motion to your answer in Question 1: what changed? Why?
- Question 4: How long did it take to reach maximum speed?
- Reset, and turn "Speed" back on.
- Stack any other item on top of the crate.
- Question 5: What item did you pick? Why?
- At the same time, start your stopwatch and press the +50N button once.
- Stop your stopwatch when the speedometer maxes out.
- Question 6: Compare the observed motion to your answer in Question 1: what changed? Why?
- Question 7: How long did it take to reach maximum speed?
- Question 8: By comparing your answers between questions 1, 3, and 6, are there any rules that you can suggest for the relationship between mass, force, and acceleration?
- Question 9: Which of Newton's laws did we investigate via this experiment?
