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 ,

What is (a) the average velocity of the car, and (b) the average speed of the car in m/s? (a) The average velocity of the car is zero (0 m/s) because xf=xi; the car ends up at the same place it starts.
