In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. ... The term "free fall" is often used more loosely than in the strict sense defined above. Thus, falling through an atmosphere without a deployed parachute, or lifting device, is also often referred to as free fall.
Free Fall Formula. Free fall means that an object is falling freely with no forces acting upon it except gravity, a defined constant, g = -9.8 m/s2. The distance the object falls, or height, h, is 1/2 gravity x the square of the time falling. Velocity is defined as gravity x time.
The factors affecting the terminal speed of a falling object include:
its mass.
its surface area.
the acceleration due to gravity, g.
