Question

what will be Newtons equations of motion for a FREE FALLING BODY?​

Answer 1

An object that is moving only because of the action of gravity is said to be free falling and its motion can be described by Newton's Second Law of Motion. With algebra we can solve for the acceleration (change of velocity) of the object which is a constant and equal to the gravitational acceleration.

Describe the forces acting on an object on earth falling through the air, and how they change from when the object is first released into the air leading to terminal velocity. The two forces acting on the object are weight due to gravity pulling the object towards earth, and drag resisting this motion.
