MOMENTUM, RATE OF CHANGE OF MOMENTUM, FORCE

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.

Check the dimensional consistency of the equation, force = "(Change in Momentum)"/"Time"

Assertion : Torque is time rate of change of a parameter, called angualr momentum. Reason : This is because in linear motion, force respresents time rate of change of linear momentum.

Which among the following statement is incorrect? (1) Momentum has both direction and magnitude (2) Momentum is a scalar quantity (3) Rate of change of momentum of an object is in direction of net force (4) Rate of change of momentum is a vector quantity.

Assertion : Slope of momentum - time graph gives acceleration Reason : Acceleration is given by rate of change of momentum .

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

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 force of 2 N is applied on a particle for 2 sec, the change in momentum will be
