The purpose of this graph is to describe the acceleration of a free-falling object as being either constant or changing; as being directed upward‚ downward or both (depending on some other variable); and as having a particular numerical value.This lab deals with the motion of an object falling freely (assuming negligible air friction) under the force of gravity. The position of a falling object will be measured as a function of time‚ and its acceleration will be determined from those data. In regard

theory they should both strike the ground at the same time; in practice the brick will always strike the ground first. The reason is because of air resistance. As the paper falls to the ground air resistance is pushing the paper up‚ this slows the acceleration of the paper. It is known that as the velocity of an object increases the air resistance acting on the object increases. If we consider jumping out of a plane and free fall towards the Earth the F.B.D. would be as follows: Now the force
