When the velocity of a body executing shm is zero its acceleration is not zero. Why?

Text Solution

AI Generated Solution

To understand why the acceleration of a body executing simple harmonic motion (SHM) is not zero when its velocity is zero, we can break down the explanation into clear steps: ### Step-by-Step Solution: 1. **Understanding SHM**: - Simple Harmonic Motion (SHM) is a type of periodic motion where the restoring force is directly proportional to the displacement from the equilibrium position and acts in the opposite direction. 2. **Key Characteristics of SHM**: ...

At what position of a body executing shm its acceleration (i) maximum and (ii) zero.

A : When the velocity of an object is zero at an instant, the acceleration need not be zero at that instant. R : In motion under gravity, the velocity of body is zero at the top - most point.

Statement-I : When velocity of a particle is zero then acceleration of particle is zero. Statement-II : Acceleration is equal to rate of change of velocity.

Assertion : We know the relation a = v. (dv)/ds . Therefore, if velocity of a particle is zero, then acceleration is also zero. Reason : In the above equation, a is the instantaneous acceleration.

Statement-1: When velocity of a particle is zero then acceleration of particle must be zero at that instant Statement-2: Acceleration is equal to a= v ((dv)/(dx)) , where v is the velocity at that instant .
