Work Can be summarized as an equation.
W = Fd
W = work F = force d = distance
Measured in J Measured in N Measured in m
Example #1: You move a 75 kg refrigerator 35 m.
This requires a force of 90 N. How much work, in
joules, was done while moving the refrigerator?

Rank the torques on the five doors shown in the figure above from least to greatest. note that the magnitude of all the forces is the same

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
