Which one of the following parameters of a particle executing uniform circular motion is directed towards center?
In simple harmonic motion, motion is executed by a particle that is subject to a force which is ___________to the displacement of the particle and is directed toward the______________.
A particle is executing simple harmonic motion of amplitude A. At a distance x from the centre, particle moving towards the extreme position received a blow in the direction of motion which instantaneously doubles the velocity. Its new amplitude will be
