Free fall and acceleration
A ball is thrown upwards, rises to its peak and eventually fall back to the original height. As the ball rises, its acceleration is upwards; as it falls, its acceleration is downwards.
False; acceleration of ALL free-falling objects is directed downwards. A rising object slows down due to the downward gravity force.
g stands for force of gravity
False; g is ACCELERATION of gravity. Force of gravity is Fgrav.
An object that is free-falling is acted upon by the force of gravity alone
True
A massive object will free fall at the same rate of acceleration as a less massive object
True; acceleration of free-falling objects is independent of mass
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.
True; if object is truly in free-fall, the speed of object will be the same at all heights
A ball is thrown upwards and is rising towards its peak. As it rises upwards, it is NOT considered to be in a state of free fall
false; any object that's rising/falling/moving horizontally/vertically is in a state of free fall
