Question description

Please fill it

It references the PHET Torque activity which can be found here:

Note that you will need Java to run this simulation. If you're using a Mac, you'll need to (1) download the .jar file by clicking on the simulation, (2) navigate to the download folder, and (3) ctrl+click -> open (do NOT just double click, as the file will not open as a security measure).

Physics Web Quest: Torque

Period ________________________

Open the Physics Animations Folder
Open torque
( )
Part I: Torque
1. Click the tab at the top that says torque
2. Set the force equal to 1 N.
3. Click Go let this run for at least 10 seconds
4. What is the torque on the wheel (include direction). Torque = 4N-m in
perpendicular direction.
5. What eventually happens to the lady bug? ___It flies off to the turntable_
6. From Newton’s second law, a force will cause an ____acceleration__
7. When considering angular motion, a torque will cause an _____angular
acceleration______ (consider both torque equations)
8. What must be the centripetal force that keeps the lady bug moving in a circle?
9. Why does this force eventually fail? ____Because of the existence of constant
value of static friction. The angular acceleration increases the centripetal force on
the lady bag.
10. Reset all, and set the force back to 1 N.
11. Observe the acceleration vector as you start. Describe how it chan...
