Question

Assertion: The average speed of a body over a given interval of time is equal to the average velocity of the body in the same interval of time if a body moves in a straight line in one direction.
Reason: Because in this case distance travelled by a body is equal to the displacement of the body.
A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If assersion is false but reason is true.

Answer 1

Correct Answer - A
When a body moves on a straight path in one direction value of distance and displacement remains same so that average speed equals the average velocity for a given time interval.
