change in acceleration is
change in velocity divided by time
the change in position is known as
displacement
what is the slope on a position time graph
the velocity of an object
what is the slope on a velocity time graph
acceleration of the object
what is the area under a position time graph
the displacement of the object
what is the only variable acting in free fall
gravity
what is the acceleration due to gravity
-9.81m/s^2
how can velocity change?(3 ways)
it can slow down
it can speed up
or it can change direction
what is a change in displacement divided by time
velocity
if velocity is in the opposite direction of acceleration what happens to speed
the object is slowing down
what is the final position minus the initial position
displacement
if velocity is in the same direction as acceleration what happens to speed
the object will be speeding up
velocity is the slope on what type of graph
velocity vs time graph
what part of a velocity vs time graph indicates displacement
the area under the v vs t graph
what are the two formulas for calculating average velocity
v= d/t or v= (vf+vi)/2
acceleration is the slope on what type of graph
velocity vs time graph
