Question

Differential equation of simple harmonic motion and its solution

Answer 1

The differential equation of linearS.H.M. is d2x/dt2 + (k/m)x = 0 where d2x/dt2 is the acceleration of the particle, x is the displacement of the particle, m is the mass of the particle and k is the force constant. ... The negative sign indicated that acceleration and displacement are in opposite direction of each other.
