Acceleration is the rate of change of velocity of an object. Thus when the velocity ( direction or magnitude) of an object changes, we say that the particle is accelerating. Mathematically it is written as
a=
The units of acceleration are m/s²
Acceleration can be positive or negative. If the velocity of an object increases, we call that as positive acceleration and if the velocity of an object decreases, we call that as the negative acceleration.
Explanation:
The kinetic energy of a particle in SHM is given by :
Where
m is the mass of a particle
A is the amplitude
x is the distance
is the angular frequency
The kinetic energy of a particle executing SHM is maximum at its equilibrium position and minimum at a maximum displacement from the equilibrium point.
