THE FIRST SEMESTER of an undergraduate physics course invariably spends a lot of time on two big ideas: The momentum principle and the work energy principle. Both deal with forces acting on an object, which often leads students to think they are similar. In a way, they are, and they play a huge role in almost everything you learn during an introduction to physics.
Before I give you a great physics question that uses these ideas, I will go over them in a super-brief physics lesson. First, the momentum principle says that a net force changes the momentum of an object where the momentum is the product of mass and velocity. Working in one dimension to avoid dealing with vectors, I can write it like this:
If you consult your introductory physics textbook, you'll see that this is essentially the same as Newton's Second Law, which states that the net force is equal to the product of mass and acceleration (where acceleration represents the change in velocity). You can rewrite the momentum principle to solve for the change in momentum (which is useful)

a small vehicle requires more forced to attain its acceleration because due to the small in mass
sorry it was the network problem and now I am continuing the answer please do not
as I said that there will be increase of pressure if the mass is small so it so the force applied by the acceleration should be more to move it so it large vehicle require less acceleration VRS small vehicle require more acceleration due to the momentum
