It is the average velocity between two points on the path in the limit that the time (and therefore the displacement) between the two points approaches zero.

In the image above, the red line is the position vs time graph and the blue line is an approximated slope for the line at t=2.5 seconds. For constant velocity motion, the slope gives the constant velocity, the average velocity, and the instantaneous velocity at every point.

Questions such as, “How long does a foot race take?” and “What was the runner’s speed?” cannot be answered without an understanding of other concepts. In this section we add definitions of time, velocity, and speed to expand our description of motion.

We can explicitly calculate the x - component of instantaneous velocity from Equation (4.3.5) by first calculating the displacement in the x -direction, Δx = x(t + Δt) − x(t) . We need to calculate the position at time t + Δt ,
