free fall an object is in free fall if it is moving under the influence of gravity.
accceleration due to gravity the acceleration of 9.8 m/sec^2 is important it is given its own name and symbol
time of flight if a problem asks for the time of flight remember that an object takes the same time goiing up as it takes coming down.
air resistance air resistance is so small it may be neglected
terminal speed the maximum speed at which an object falls when limited by air friction
slope slope of a graph is equal to the ratio of rise to run
delta translates to the change in
constant acceleration has the same speed that changes by the same amount every sec
uniform acceleration motion with constant acceleration appears as a sloped straight line on a speed versus time graph
