Formula for Average Acceleration
|
Average acceleration = change in velocity / change in time
|
|
|
Change in Velocity equals
|
Velocity of final - Velocity of initial
|
|
|
Acceleration due to Gravity equals
|
-9.80m/s^2
|
|
|
formula for Velocity with constant Acceleration
|
V-initial^2 = V-initial^2 + 2a(d-final--d-initial)
|
|
|
formula to find the displacement of an object moving with constant acceleration
|
d-final = d-initial + (V-initial x time) + 1/2a (t^2)
|
|
|
formula to fund the displacement of a free falling object
|
d-final = d-initial + (V-initial x time) + 1/2 (-9.8 m/s^2)(t^2)
|
|
|
found by drawing a tangent line on the velocity-time graph at a selected point
= the slope |
instantaneous acceleration
|
|
|
the rate at which an object's velocity changes
|
acceleration
|
|
|
change in velocity during some measurable time interval divided by that time interval
|
average acceleration
|
|
|
the motion of a body when air resistance is negligible and action can be considered doue to gravity alone
|
free fall
|
