Chapter 8, "Motion in One Dimension"

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 Dx and time interval t.

Acceleration

Equation 1

v_f = v_i + at

Equation 2

for constant acceleration only.

Equation 3

Dx = ½(v_i + v_f)t

Equation 4

Dx = v_it + ½at²

Equation 5
