## Exploration 11.1: Torque

Please wait for the animation to completely load.

Drag the tip of the force arrow **(position is given in meters and force is given in newtons)**. The **red arrow is the radius**, on which the force acts, and the **dark green arrow is the force**. The light green arrow also represents the force and is there to help illustrate the angle between **r** and **F**. Restart.

- When is the cross product zero?
- What is the angle between
**r**and**F**that goes in r F sin(θ)? - Is there anything missing in this representation of the torque?
- Does the assignment of
**r**and**F**matter? In other words, if**r**was**F**and**F**was**r**, would the torque be the same?

Physlets were developed at Davidson College and converted from Java to JavaScript using the SwingJS system developed at St. Olaf College.
