Newton’s First Law

Newton's first law of motion is often stated asAn object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.This picture is an example of Newton’s first law because the car was in motion and when I applied the brakes the force of the road on the locked wheels provided an unbalanced force, this changed the cars state of motion. Unfortunately though there is no unbalanced force acting upon the girl in the car her body continued to move forward because there was no unbalanced force to change her state of motion.

Newton’s Second Law

Newton's second law of motion can be formally stated as follows:The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.This verbal statement can be expressed in equation form as follows:a = Fnet / mThis picture represents Newton’s second law because my sister’s acceleration dependent upon the net force that was directed on her as I pushed her and her mass.

Newton’s Third Law

Newton’s third law is often stated as For every action, there is an equal and opposite reaction.As I am excreting force on the tack line it is exerting and equal force in the opposite direction which is allowing me to be able to be balanced.
