PHXI03:MOTION IN A STRAIGHT LINE
362150
Statement A : A particle may be momentarily at rest and yet have non - zero acceleration. Statement B : The zero velocity of a particle at any instant does not necessarily imply zero acceleration at that instant
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
A particle may be momentarily at rest and yet have non - zero acceleration. For example, freely falling particle has zero velocity at its uppermost point but the acceleration at that instant continues to be the acceleration due to gravity. Option (3) is correct.
PHXI03:MOTION IN A STRAIGHT LINE
362151
Assertion : A body may be accelerated even when it is moving at uniform speed. Reason : When direction of motion of the body is changing then body may have acceleration.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Acceleration is a vector quantity that includes changes in speed or changes in direction. Even if a body is moving at a constant speed, it can still be accelerating if its direction of motion is changing. Changing direction implies a change in velocity, and therefore acceleration. This is because velocity is a vector quantity that includes both speed and direction. The reason provides a correct explanation for why the assertion is true. So correct option is (1).
