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 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 Equation 5
