An object that is free-falling is acted upon by the force of gravity alone.A falling skydiver which has reached terminal velocity is considered to be in a state offree fall.A ball is thrown upwards and is rising towards its peak. As it rises upwards, it is NOTconsidered to be in a state of free fall.An object in free fall experiences an acceleration which is independent of the mass ofthe object.A ball is thrown upwards, rises to its peak and eventually falls back to the originalheight. As the ball rises, its acceleration is upwards; as it falls, its acceleration isdownwards.A ball is thrown upwards, rises to its peak and eventually falls back to the originalheight. The speed at which it is launched equals the speed at which it lands. (Assumenegligible air resistance.)A very massive object will free fall at the same rate of acceleration as a less massiveobject.The value of g on Earth is approximately 9.8 m/s2.The symbol g stands for the force of gravity. A free falling object is an object that is falling under the sole influence ofgravity. Any object that is being acted upon only by the force of gravity issaid to be in a state of free fall.

A free falling object is an object that is falling under the sole influence of gravity. Any object that 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 that are true of free-falling objects:Free-falling objects do not encounter air resistance.All free-falling objects (on Earth) accelerate downwards at a rate of 9.8 m/s/s (often approximated as 10 m/s/s for back-of-the-envelope calculations). Which of the following statements about free fall and the acceleration of gravity are TRUE? List all that apply. There are 5 correct selections. *

A pilot is flying a plane at 220 m/s and an altitude of 500 meters. If she needs to deliver supplies via air drop, how far away from the target should she release the cargo? The cargo's parachute slows the average acceleration of gravity to 0.75 m/s2. Answer in kilometers.(In reality, a parachute significantly reduces the terminal velocity, so it won't accelerate very long. But let's keep it simple and assume the cargo accelerates the whole way.)
