Assertion : A body can have acceleration even if its velocity is zero at a given instant of time.
Reason : A body is momentarily at rest when it reverses its direction of motion.

Statement I: A body can have acceleration even if its velcity is zero at a given instant . Statement II: A body is momentarily at rest when it reverses its direction of velocity.

Can a body have acceleration without having velocity?

STATEMENT - 1 : If the body is moving in the opposite direction of positive motion, then its speed is negative. STATEMENT - 2 : A scalar quantity is one that must be dimensionless. STATEMENT - 3 : A body is momentarily at rest when it reverse its direction of motion.

The acceleration of a body is zero, what is the nature of its distance-time graph ?

Assertion: If a body is momentarily at rest, it means that force or acceleration are necessarily zero at that instant. Reason: Force on a body at a given time is determined by the direction of motin only.

Assertion: A body having non zero acceleration can have a constant velocity. Reason: Acceleration is the rate of change of velocity.

Assertion : A body may be accelerated even when it is moving uniformly. Reason : When direction of motion of the body is changing then body may have acceleration

Can the motion of a body be accelerated even when it is moving unifromly ?
