What does the negative sign in F = - kx mean? A) The displacement is in the opposite direction.

B) The spring constant is small.

C) The force is opposite the displacement.

D) The velocity is slowing down.

A because F=ma

for F to be - ve, a must be - ve and a is rate of change of velocity and velocity is rate of change of displacement so displacement must be negative for velocity to be negative for acceleration to be negative for F to be negative
