SHM- A particle executes S.H.M if  𝛼 ∝ -𝓨 . Negative sign shown that acceleration(a) is always directed in the direction opposite to that of its displacement (y ).

Displacement-of a body executing S.H.M is the maximum distance travelled by the body in a given instant from its mean or equilibrium position.

Amplititude-of a body executing S.H.M is the maximum
