. A falling skydiver which has reached terminal velocity is considered to be in a state of free fall
F
A ball is thrown upwards and is rising towards its peak. As it rises upwards, it is NOT considered to be in a state offree fall
F
A ball is thrown upwards, rises to its peak and eventually falls back to the original height. As the ball rises, its acceleration is upwards; as it falls, its acceleration is downwards.
F
The symbol g stands for the force of gravity.
F
A ball is thrown upwards, rises to its peak and eventually falls back to the original height. The speed at which it is launched equals the speed at which it lands. (Assume negligible air resistance.)
T
A very massive object will free fall at the same rate of acceleration as a less massive object.
T
An object in free fall experiences an acceleration which is independent of the mass of the object.
T
An object that is free-falling is acted upon by the force of gravity alone
T
The value of g on Earth is approximately 9.8 m/s2.
