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.

A

If both assertion and reason are trure and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanations of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason is false

Text Solution

Verified by Experts

The correct Answer is:
(c )
Change in the direction of the velocity also produces acceleration as in the case of circular motion. The change in the magnitude or direction of the velocity or both can produce acceleration.

Assertion : The average speed of an object is greater than or equal to the magnitude of the average velocity over a given time interval. Reason : The two are equal only if the path length is equal to the magnitude of displacement.

Asserion : The acceleration of an object at a particular time is the slope of the velocity-time graph at that instant of time. Reason : For uniform motion acceleration is zero.

The direction of velocity continuously changes in

Assertion : Acceleration of a moving particle can change its direction without any change in direction of velocity. Reason : If the direction of change in velocity vector changes, the direction of acceleration vector also changes.

Is it possible for a uniformly accelerating object to change its direction of velocity ?

Assertion : An object may have varying speed without having varying velocity. Reason : If the velocity is zero at an instant, the acceleration may not be zero at that instant.

Assertion : The equation of motion can be applied only if acceleration is along the direction of velocity and is constant. Reason : If the acceleration of a body is constant then its motion is known as uniform motion.
