PowerPoint Presentation - 5. Universal Laws of Motion
... • Any object which is being acted upon only by the force of gravity is said to be in a state of free fall. There are two important motion characteristics which are true of free-falling objects: – Free-falling objects do not encounter air resistance. – All free-falling objects (on Earth) accelerate d ...
