Objects can move from one space position to another {displacement, motion}|. Displacement has direction and amount and so is vector.
velocity
Displacement s equals average velocity v times time t: s = v*t. Distance change ds equals constant velocity v times time change dt: ds = v * dt.
Displacement s equals initial velocity vi times time t plus one-half acceleration a times time t squared: s = vi * t + 0.5 * a * t^2. Distance change ds equals initial velocity vi times time change dt plus half acceleration a times square of time change dt during acceleration: ds = vi * dt + 0.5 * a * dt^2.
graph
If acceleration is zero, displacement versus time is straight line. If acceleration is positive, displacement versus time curves up.
