Equations for constantly accelerated straight-line motion
Form to use when accelerating object has initial velocity
?x = 1/2 (vi + vf) ?t
vf = vi + a?t
?x = vi + 1/2a(?t)2
vf2 = vi2 + 2a?x
Form to use when accelerating object starts from rest
?x = 1/2vf?t
vf = a?t
?x = 1/2a(?t)2
vf2 = 2a?x
a is acceleration in m/s2
vi and vf are initial and final velocities, respectively, in m/s
t is time in s
x is displacement in m
NOTE: All the question marks (?) are supposed to be deltas, I don't know why they don't show here
