Detailed Solution

According to Newton's second law of motion, the rate of change of momentum is equal to the applied force. 

Impulse: The change in momentum is called impulse. 

Pressure: The force per unit area is called pressure. 

Work: The dot product of force and displacement is equal to work done.

Newton's Second law of motion: The rate of change of momentum of any object is directly proportional to the applied force on the body.

Force
(F)=ΔPΔt
Where ΔP= Change in momentum and Δt= change in time taken
Momentum (P): The product of mass and velocity is called momentum.
Momentum (P)=mass(m)× Velocity (v)
The rate of change in momentum of an item is proportional to the applied resultant force and is in the same direction as the applied resultant force. The rate of change of momentum is equal to the resulting force.
