This equation can be derived by combining two equations for average velocity. Average velocity is defined as displacement divided by the time during which that displacement occurred: v a v g = x − x 0 t
Although speed and velocity are often words used interchangeably, in physics, they are distinct concepts. Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d ...
