The rate of change of momentum of a body is proportional to the resulting force and occurs in the direction of the force.
In other words, force is equal to mass times acceleration.
F = ma
This law provides the definition and calculation of force through mass and acceleration.
To help the understanding of this concept, replace force with weight. Weight is a force that we feel on Earth, caused by gravity and our mass. Since gravity is calculated using the units of , therefore it is an acceleration constant. We could come to the conclusion that:
W = mg
