Newton’s Law of Motion
PHXI05:LAWS OF MOTION

363489 A particle is moving with a constant speed along a straight line path. A force is not required to

1 Decrease the momentum
2 Increase its speed
3 Keep it moving with uniform velocity
4 Change the direction
PHXI05:LAWS OF MOTION

363490 Assertion :
If two objects of different masses have same momentum, the lighter body possess greater velocity.
Reason :
For all bodies momentum always remains same.

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.
