A student investigates the conservation of energy using a trolley rolling down an inclined ramp. The student has already set up a light gate and data logger at the bottom of the ramp to measure the final velocity of the trolley. State two other measurements the student must make to determine the loss in gravitational potential energy and the gain in kinetic energy.
