How is the law of acceleration applied in accomplishing a task in relation to a person's ability and the effort exerted?

Newton's second law of motion states that the force is equal to the product of the mass and acceleration. It can mathematically be expressed as,
                                      F  = m x a
When this equation is transformed to solve for acceleration, this becomes,
                                   a = F / m
The equation suggests that for an object to move, force has to be exerted.
