What is force?
... • Any passenger not wearing a safety belt continues to move forward at the same speed the car was traveling. • Within about 0.02 s (1/50 of a second) after the car stops, unbelted passengers slam into the dashboard, steering wheel, windshield, or the backs of the front seats. ...

Simple harmonic motion
... A TRAMPOLINE exerts a restoring force on the jumper that is directly proportional to the average force required to displace the mat. Such restoring forces provide the driving forces necessary for objects that oscillate with simple harmonic motion. ...

... Choosing this option suggests that the candidate realises that the ball has some momentum when released, but that it dissipates as it falls under gravity. It may be, if it has not been stressed initially that air resistance can be ignored, that the candidate has the correct understanding, but assume ...
