Several physical situations are described below. For each situation, simplify the work-energy equation by canceling any zero terms and any energy terms (whether KE or PE) which are unchanging. Explain each term which gets canceled. A ball starts from rest at an elevated position along an inclined plane and rolls to the ground below. Assume that the effect of friction and air resistance is negligible. Simplification of Work-Energy Equation KEi + PEi + Wnc = KEf + PEf

A small block, with a mass of 4 kg, starts from rest at the top of the apparatus shown above. It then slides without friction down the incline, across the first level section, around the loop and then onto the final level section on the right. It then collides with a spring and compresses it, which momentarily brings the block to a stop. The maximum height of the incline is 5 m, the radius of the loop is 1.0 m and the spring constant is 120 N/m.
