A student investigates energy transfers by releasing a glider from the top of a tilted air track. A light gate at the bottom of the track measures the time taken for a card of known length on the glider to pass through, which allows the final speed to be calculated.
State two other measurements the student must make to determine the decrease in gravitational potential energy and the increase in kinetic energy of the glider.
