Displacement with Constant Velocity

displacement = velocity * time ( D = v * t )

for any constant velocity v .

Displacement Between Frames

new_position = old_position + velocity * time

where time is one frame (usually of a second).

Average Velocity

for any displacement D x and time interval t .

Acceleration

Equation 1

v _f = v _i + at

Equation 2

for constant acceleration only.

Equation 3

D x = ½( v _i + v _f ) t

Equation 4

D x = v _i t + ½ at ²
