Work Done by a Constant Force
... The force exerted by the catcher is opposite in direction to the displacement of the ball, so the work is negative. Or using the definition of work (W = F d cos ), since = 180o, then W < 0. Note that because the work done on the ball is negative, its speed decreases. Follow-up: What about the wo ...
