What actually the momentum means and what is gives??

Momentum simply means mass in motion.

momentum = mass x velocity

p= m×v

Where p is momentum, m is the mass of an object in kg and v is the velocity of the object in m/s

Momentum is a vector quantity.

Force is a comparative sort of amount to vitality: the primary motivation behind why it's imperative is that it's saved. Early physicists worked out by trial that the amount mv⃗ is by all accounts rationed in crashes of inflexible bodies. Out of all the conceivable amounts that could be developed from the mass and speed of a body, physicists picked four to concentrate on: the dynamic vitality, 12mv2 and the three parts of force, mv⃗. Notice for instance that no one thinks about the amount m3v2, since there's no protection law for it.

There are different types of energy other than mv⃗; the electromagnetic field, for example, additionally conveys its own force, with the neighborhood thickness ϵ0(E⃗×B⃗). Delicate instruments can distinguish the force of light, which is an electromagnetic wave. The motivation behind why we call this energy, just as it had indistinguishable nature from mv⃗, is that we need to incorporate it in the recipe for aggregate force all together for aggregate force to be really saved. Generally force can be moved among particles and the electromagnetic field, with nor being saved separately.

In this manner, eventually, energy is the thing that it must be characterized as so as to be rationed. You can consider it estimating the settled "amount of movement" present in a framework, the same number of early physicists did, as long as you recall that there seems to be "potential energy" that likewise should be represented.
