Q4 of 58 Page 36

The velocity-time graph of a particle falling freely under gravity would be a straight line parallel to the x-axis.

False

Since the body is experiencing a force. It will accelerate and velocity will change, hence it will not be parallel to the x-axis.

Acceleration can get negative value also.

Distance covered by a particle never becomes zero between any interval of time but displacement becomes zero.

If the velocity-time graph of a particle is a straight line inclined to time axis then its displacement – time graph will be a straight line?

Assertion: The accelerated motion of an object may be due to change in magnitude of velocity or direction or both of them.

Reason: Acceleration can be produced only by ca hange in magnitude of the velocity it does not depend on the direction.
