If a car travels one mile east and then returns one mile west, to the same position, the total displacement is zero and so is the average velocity over this time period. Displacement is measured in units of length, such as meters or kilometers, and velocity is measured in units of ...

So these special cases of constant velocity and of constant acceleration are worth considering in more detail. Movement in one dimension If an object is moving in a straight line, and if we measure its position along that line, then its position, velocity and acceleration can all be ...
In the reconstruction a rigid seat, a rigid footrest, a 2-point shoulder belt, and a 2-point lap belt were simulated, see Fig. 2. Lacking specific belt dimension and stiffness data from the experiments, a baseline belt (as described previously) was implemented. A retractor without force ...
