Question
Physics Question on Motion in a straight line
The accelerated motion of an object may be due to change in magnitude of velocity or direction of velocity or both. Acceleration can be produced only by change in the magnitude of the velocity.
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 both assertion and reason are false
Answer
If assertion is true but reason is false
Explanation
Solution
Change in the direction of the velocity also produces acceleration as in the case of circular motion. The change in the magnitude or direction of the velocity or both can produce acceleration.
