If the instantaneous velocity of a particle is zero, will its instantaneous acceleration be necessarily zero

What is instantaneous velocity?

Define instantaneous acceleration with example.

The instantaneous velocity of a body can be measured

Assertion: The average velocity of a particle is zero in a time interval. It is possible that the instantaneous acceleration is never zero in the interval. Reason: The magnitude of average velocity in an interval is equal to its average speed in that interval.

A particle is moving in a straight line. All the physical quantities are to be measured in MKS system. Square of the magnitude of its instantaneous velocity is found to be ten times its instantaneous displacement . What is the acceleration of the particle?

If the total mechanicla energy of a particle is zero is its linear momentum necessarily zero? Is it necessarily nonzero?

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.

Give examples where a. the velocity of a particle is zero buts its acceleration is not zero. b.the velocity is opposite in direction to the acceleration, c. the velocity is perpendicular to the acceleration.
