Physics · Uniform and non-uniform motion, average speed and instantaneous velocity
Assertion Average velocity of the body may be equal to its instantaneous velocit
Assertion Average velocity of the body may be equal to its instantaneous velocity at all points of time. Reason If a body is having uniform motion in one dimension, then velocity is constant and average velocity can be equal to instantaneous velocity
- A. Both Assertion and Reason are true and Reason is the correct explanation for Assertion.
- B. Both Assertion and Reason are true but Reason is not the correct explanation for Assertion.
- C. Assertion is true, but Reason is false.
- D. Assertion is false, but the Reason is true.
Step-by-step solution
The assertion is true because if a body moves with constant velocity (uniform motion), its instantaneous velocity at every instant equals that constant value, and the average velocity over any time interval also equals that same value. The reason correctly states that for uniform motion in one dimension, velocity is constant, leading to equality of average and instantaneous velocity. Thus the reason directly explains the assertion.
