#### Explanation:

#"Force" = "mass" xx "acceleration"#

Rate of change of momentum is directly proportional to force.

Change in momentum can be

#m * v_2 - m * v_1 = m * Deltav# , where#v_2# and#v_1# are different velocities.

Rate of change of momentum is

#d/(dt)(mv) = m * (dv)/(dt)#

But

#F = m * a#

#### Explanation:

Newton's he second law of motion describes how the motion of an object behaves under the influence of an external force. Here

The law can also be written in a couple of different ways. since the acceleration is the change in velocity, and velocity the change in place, we can write

This means

Since the total mass of an object is usually constant, we can pull

This can be used to show that in an isolated system the total momentum of all objects is conserved, which is an important result in classical physics.
