Physics · MOTION IN A STRAIGHT LINE

हिन्दी

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): For an object in uniform motion, the average velocity over any time interval is equal to its instantaneous velocity. Reason (R): In uniform motion, the velocity is constant at every instant of time. In the light of the above statements, choose the correct answer from the options given below:

  1. Both (A) and (R) are true and (R) is the correct explanation of (A).
  2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
  3. (A) is true but (R) is false.
  4. (A) is false but (R) is true.

Correct answer · Option 1

Both (A) and (R) are true and (R) is the correct explanation of (A).

Explanation

Since velocity does not change in uniform motion, both average and instantaneous velocities are identical at all points.
