Newton’s Second Law of Motion states that: in the presence of a net force, an object experiences an acceleration or F = ma.

The implication being that when a net force interacts with inertia it will change the velocity of an object by changing either its speed or its direction. Such a change in velocity is called acceleration. So, we can say that a net force gives rise to acceleration. More simply, and as Newton put it: F=ma, where “F” (force) and “a” (acceleration) are both vector quantities, and “m” is the object’s mass.
