... Have a student walk across the front of the room, carrying the 10 kg brick, at a constant speed. How much work did they do? What is the equation for the change in PE of the brick? Change in PE = PE2 – PE1 = (mgh2 – mgh1) But h2 = h1, so no PE is added or change in PE = 0. So no work is done because ...
