More precisely, the first law defines the force qualitatively, the second law offers a quantitative measure of the.
The second law states that the acceleration of an object is dependent upon two variables the net force acting upon the object and the mass of the object. Gravity is a force of attraction that keeps objects on the ground. The direction of acceleration is the same as the direction of the net force.
