Assertion: Newton's second law of motion given the measurement of force. Reason: According to Newton's second law of motion, force is directly proportional to the rate of change of momentum.

A : Newton's second law of motion gives the measurement of force. R : According to second law of motion, force is directly proportional to the rate of change of momentum.

Newton's first law of motion defines force and Newton's second law of motion gives us a measure of force. Comment.

Assertion : Distance-time graph of the motion of a body having uniformly accelerated motion is a straight line inclined to the time axis. Reason : Distance travelled by a body having uniformly accelerated motion is directly proportional to the square of the time taken.
