Assertion: An object can have constant speed but variable velocity. Reason: Speed is a scalar but velocity is a vector quantity.

Can a body have acceleration without having velocity?

An object may have (a). Varying speed without having varying velocity (b). Varying velocity without having verying speed (c). Non zero acceleration without having varying velocity (d). Non zero acceleration without having varying speed.

Can a body have zero velocity and finite acceleration?

Assertion : At object may fall with a constant velocity. Reason : This happens when acceleration of the object is equal to accelertion due to gravity.

The question given below consist of an assertion and the reason . Use the following key to choose appropriate answer: Assertion : At the highest point velocity of the projectile is zero Reason : At the highest point of trajectory acceleration of the particle becomes zero for an instant .

Assertion : The accelerated motion of an object may be due to change in magnitude of velocity or direction of velocity or both. Reason : Acceleration can be produed only by change in the magnitude of the velocity.
