Question

During a storm, a student sees a rock fall from a cliff and smash into another rock below. which of the following is an application of Newton's Second law of Motion? A - The gravitational attraction of Earth initially pulled the rock toward the ground. B - the mass of the rock is related to the force with which it hit the ground. C - The rock's inertia is increased on collision.

Answer 1

Since Newton's second law states that Force = mass x acceleration ($F=ma$), B is the correct description of an application.
