Speed

• when a distance l is traveled during a time interval Δt is

• the time derivative of the displacement (a limit as the time interval approaches Zero)

• is the absolute value of the velocity vector. For a moving object, speed is always positive.

• finding the rate of change of a function with respect to one of its variables
