Question
Write down the expression for the instantaneous position of particle vibrating in simple harmonic motion.
Solution
Instantaneous position of the particle vibrating in S.H.M is given by,
y = A sin ωt
where,
y = displacement of the body from the mean position,
a = maximum displacement or amplitude of the body,
is the angular frequency of the wave, and
t is the time of oscillation.
y = A sin ωt
where,
y = displacement of the body from the mean position,
a = maximum displacement or amplitude of the body,

t is the time of oscillation.
