velocity
the speed of an object in a given direction
acceleration
the rate at which velocity changes over time
complete the equation. vt =
vt = vi + at
how can initial velocity be denoted?
v0 or vi
how can final velocity be denoted?
vt or vf
complete the equation. xt =
x0 + vit + ½ at2
complete the equation. vf2 =
vf2 = vi2 + 2ad
what is the equation for average velocity?
v bar = vf + vi / 2
what is the equation for displacement?
d = (vf + vi / 2)t
how to find average velocity?
change in displacement / change in time
how to find average acceleration?
change in velocity / change in time (in m/s2)
