Name: Solutions Prelab Questions on Conservation of Energy 1. In the two dimensional motion part of today’s lab, you will make measurements of a two-dimensional trajectory such as that shown below. Please state qualitatively how the value of kinetic energy of the moving puck changes as the puck is moving from A to B, and also for the motion from B to C. (Consider not just the endpoints but also the positions between endpoints) From A to B, K of the moving puck first decreases until the moving puck has the smallest separation from the fixed puck, after which K of the moving puck increases. From B to C, K of the moving puck

Unformatted text preview: increases all the time. 2. The graph below plots potential energy vs. separation between the two pucks as in today’s experiment. Please use the line in the graph to determine where the force acting on the movable puck is largest. (Consider only the range of r values plotted in the graph) At A (r=0.12 m), the force acting on the movable puck is largest because the movable puck is closest to the fixed puck and its potential energy is largest. Where there is lots of potential energy, there is the ability to create lots of kinetic energy by the law of conservation of energy....
