Answer fast motion
Dear Student
In uniform motion the object moves with uniform velocity, the magnitude of its velocity at different instance i.e., at t = 0, t =1, sec, 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.
So
Assertion is correct, reason is incorrect.
