Assertion :Velocity-time graph for an object in uniform motion along a straight path is a straight line parallel to the time axis. Reason: In uniform motion of an object velocity increases as the square of time elapsed.

Solution
The correct option is C Assertion is correct but Reason is incorrect
In uniform motion the object moves with uniform velocity, the magnitude of its velocity at different instant i.e. at t=0,t=1sec,t=2sec,.... will always be constant. Thus velocity-time graph for an object in uniform motion along a straight path is a straight line parallel to time axis.
