This document discusses Newton's Laws of Motion and their application to sprinting. It introduces Asafa Powell, a Jamaican sprinter, and covers Newton's 1st Law of inertia and an object's tendency to remain in motion unless acted upon by an outside force. It also briefly outlines Newton's 2nd Law that acceleration is produced by an applied force and is directly proportional to the force but inversely proportional to the mass. Finally, it mentions Newton's 3rd Law of equal and opposite reactions and defines linear motion as movement in a straight line from one point to another.
