What is the formula for average acceleration
Change in velocity/change in time
Formula for change in velocity
Final velocity - initial velocity
What is the constant-acceleration velocity equation?
vf = vi+at
(vf = final velocity, vi = initial velocity, a = acceleration, t = time)
What is the formula for change in velocity when acceleration is constant?
Change in velocity = at (acceleration * time)
What is the displacement formula for constant acceleration from rest?
displacement = 1/2(constant acceleration)(time²)
What is the average velocity formula for constant acceleration
(vi+vf)/2
How do you find displacement using average velocity
displacement = avg;v * t
What does the slope of a velocity-vs-time graph represent?
acceleration
What does the area under a velocity-vs-time graph represent?
Displacement
What does the area under an acceleration-vs-time graph represent?
