A simple harmonic motion is represented by `x(t)= Acosomegat`A SHM has ampliitude A and the time period T, what is the time take to travel from `x=A` to `x=A/2`

A simple harmonic motion is represented as x=A cos omegat . Obtain the expression for velocity and acceleration of the object and hence prove that acceleration is directly proportional to the displacement.

The displacement in simple harmonic motion can be represented as x(t)=Acos(omegat + phi) ,where phi is the phase constant. Define A in the equation.

Use your definition to explain how simple harmonic motion can be represented by the equation y=a sin omega t Show that the above equation is dimensionally correct

Time period of a particle in simple harmonic motion (SHM) depends on the force constant K and mass m of the particle. A man with his wristwatch on his hands falls from the top of a tower.Does the watch give the correct time during the free fall?Why?
