A student investigates the conservation of mechanical energy using a toy car sliding down a curved, frictionless track. A light gate and data logger are positioned at the lowest point of the track to measure the final speed of the car as it exits the curve.
State two other measurements the student must make to determine the loss in gravitational potential energy and the gain in kinetic energy.
