(Show all work, proper units and sig figs.) 1. Please answer the following questions, a) In the Friction experiment. Compare My to W Which is larger? Why so ? b) In the Collisions experiment. Was the collision Elastic or Inelastic? Explain. c) In the Conservation of Energy experiment. The total energy seems to decrease after every bounce. Does that mean energy is not conserved? Where did that energy go? d) In the Newton's 2nd Law for Rotation experiment, if you make an error in measuring the diameter of the Drum, such that your measurement is larger than the actual diameter, how will this affect your calculated value of the Inertia of the system? Will this error make the calculated Inertia larger or smaller than the actual? (circle one). Explain.
