Question
Physics
Your class is asked to plan an investigation to demonstrate the conservation of energy. Two groups each wrote their own plan.We will use a battery powered toy car to demonstrate conservation of energy. It will roll across a flat table three times. Keeping the distance constant, we will time it with a stopwatch. We will calculate its average speed, and from there, determine how much energy it had.We will roll a ball down a ramp. Photogates will measure the ball's speed at 10 places along the ramp. We will use a ruler to measure the ball's height at those same 10 places. Then we will graph the kinetic energy vs. displacement and the potential energy vs. displacement to compare them. Which group best completed their objective, and why?
