It is important to understand drag, as it affects the distance an object is able to travel if it is not influenced by outside forces, such as a cannons projectile. The equation for drag is shown below. F=pCA/2 v^2 p = The density of the air. C = The drag coefficient of the…

The archer’s paradox is this bending of the arrow around the bow as it is being loosed…

    recognized that his first law needed some additional explanation because most of the motion we observe around us undergoes changes and is the result of one or more applied forces; therefore, Newton wrote a Second Law of Motion which relates force, mass, and acceleration.
