Question

A particle starts from the mean position and moves towards the positive extreme in SHM. Which statements about its motion are correct?

G1 Physics · Accepted Answer

Using x = A sinωt, the phase at A/2 is π/6, so the time from 0 to A/2 is T/12. The phase from A/2 to A changes by π/3, so that interval is T/6. Because speed depends on position, equal displacement intervals do not generally take equal times. The speed decreases from Aω at the mean position to zero at the extreme. Therefore all four statements are correct.
