A body having zero velocity will necessarily have zero acceleration.
true or false??

Solution

False

example 1 Just throw a ball vertically upwards in the air. It is constantly accelerating (decelerating, in this case) with 'g' in the downward direction. And at the topmost point, when it's velocity goes down to zero for an instant, it's still accelerating (with same 'g' in the downward direction).

example 2 Consider a body moving along positive X direction with a velocity of 10 m/s.
It has a constant acceleration of 2 m/s^2 in the negative X direction (Essentially retardation).
At exactly 5 seconds, the velocity of the particle will be zero, but it'll still have a constant acceleration of 2 m/s^2 in the negative X direction.

Read each statement below carefully and state with reasons and examples, if it is true or false;
A particle in one-dimensional motion
a) with zero speed at an instant may have non-zero acceleration at that instant
b) with zero speed may have non-zero velocity,
c) with constant speed must have zero acceleration,
d) with positive value of acceleration must be speeding up.

Q. Assertion :A particle may be momentarily at rest and yet have non-zero acceleration Reason: The zero velocity of a particle at any instant does not necessarily imply zero acceleration at that instant.

can a body have constant acceleration but zero velocity

Q. Can a body have zero velocity and finite acceleration?

S_{1}

: A body having non-uniform velocity will have zero acceleration.

S_{2}

: A charge particle is free to move in an electric field. It will travel along a line of force, if it has some initial velocity in the direction of a non-zero acute angle with the line of force.

S_{3}

: Stationary waves are called 'stationary' because in them everything remains at rest. Find the correct alternative from the following(
