If an object is in equilibrium:
☐ the net force on it must be zero

☐ neither of the above
Ralph noticed that both torque and work are
obtained by multiplying a force times a distance. He wants to know: how are they different?
they have the same units? What can you tell Ralph to help him out?
The comments in the next next two boxes go into a big, mostly anonymous text file that I skim through before the morning lecture, using the comments to help me plan class discussion.
