Assertion: A given force applied in turn to a number of different masses may cause the same rate of change in momentum in each but not the same acceleration to all.
Reason: `F=(dp)/(dt)` and `a=F/m`

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

Statement I: The greater the rate of the change in the momentum vector, the greater the force applied. Statement II: Newton's second law is vec(F)=(dvec(p))/(dt) .

A body of mass 'm' at rest is applied with a force F = (2 + 4t)N. The change in momentum of the interval one second to two second is

Assertion: A constant force F is applied on two blocks and one spring system as shown in figure. Velocity of centre of mass increases linearly with time. Reason: Acceleration of centre of mass is constant.

Assertion: A constant force F is applied on two blocks and one spring system as shown in figure. Velocity of centre of mass increases linearly with time. Reason: Acceleration of centre of mass is constant.

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