Kinematics Question 99
Question: Assertion : Velocity-time graph for an object in uniform motion along a straight path it’s a straight line parallel to the time axis. Reason : In uniform motion of an object velocity increases as the square of time elapsed.
Options:
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.
Show Answer
Answer:
Correct Answer: C
Solution:
In uniform motion the object moves with uniform velocity, the magnitude of it’s 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 it’s a straight line parallel to time axis.
