Newton’s second law of motion addresses the relationship between what two variables that influence the force on a body?
a. mass and acceleration b. acceleration and inertia c. inertia and mass
d. acceleration and velocity

A. Mass and acceleration

Explanation:

According to Newton's second law of motion, the resultant force is directly proportional to the rate of change in momentumTherefore; F = ma , where F is the resultant force, m is the mass, and a is the acceleration of the body.Resultant force depends on the acceleration and the mass of a body in motion, an increase in acceleration causes a corresponding increase in resultant force. A body with higher mass will have a larger strong force if the acceleration is kept constant.

Protons have a positive charge and, collectively, give an element its atomic number.
