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.
