Simple Harmonic Motion - Multiple Choice Questions

Q14. Which one of the following gives the phase difference between the particle velocity and the particle displacement in simple harmonic motion?

A /4 rad
B /2 rad
C 3/4 rad
D 2 rad

Look at the graphs - the peaks of displacement and velocity are 'out' from each other by a quarter of a cycle.

One cycle is 2 radians therefore they are 'out' by /2 radians.
