In simple harmonic motion, the acceleration of the system, and therefore the net force, is proportional to the displacement and acts in the opposite direction of the displacement. 3 Velocity and Acceleration Since we have x ( t) we can just differentiate once to get the velocity and twice to get the acceleration. Here we have a direct relation between position and acceleration. The differential equation of linear S.H.M. velocity is: v (t)=cos (t) acceleration is: a (t)=-sin (t) function x (t): above x-axis describes position of the mass below the vertical equilibrium point, wich (below) is the positive direction of vector x. suppose I look at the movement between t=0 and t=T/4: when the mass is below the vertical equilibrium line and is moving to the ground. Here's the general form solution to the simple harmonic oscillator (and many other second order differential equations).

You can see that whenever the displacement is positive, the acceleration is negative. Simple harmonic motion (SHM) is an oscillatory motion for which the acceleration and displacement are pro-portional, but of opposite sign.
