Question

In linear SHM:

A. restoring force is directly proportional to displacement,

B. acceleration and displacement are opposite in direction,

C. velocity is maximum at mean position,

D. acceleration is minimum at extreme points. Choose the correct set.

G1 Physics · Accepted Answer

In SHM: F = -kx and a = -ω²x Thus the restoring force magnitude is proportional to displacement and acceleration is opposite to displacement. At the mean position, speed is maximum. At the extreme positions, |a| = ω²A is maximum, not minimum. Therefore A, B and C are correct. Hence option C.
