Chapter 2 Motion In A Line Explain the relationships between instantaneous velocity, average velocity, instantaneous speed, average speed, displacement, and time. calculate velocity and speed given initial position, initial time, final position, and final time. derive a graph of velocity vs. time given a graph of position vs. time. interpret a graph of velocity vs. time. The average speed is 12 km h. the displacement for the round trip is zero, since there was no net change in position. thus the average velocity is zero. another way of visualizing the motion of an object is to use a graph. a plot of position or of velocity as a function of time can be very useful. The graph of position versus time in figure 2.46(a) is a curve rather than a straight line. the slope of the curve becomes steeper as time progresses, showing that the velocity is increasing over time. the slope at any point on a position versus time graph is the instantaneous velocity at that point. In symbols, average velocity is. ¯v = Δx Δt = xf −x0 tf −t0 v ¯ = Δ x Δ t = x f − x 0 t f − t 0. the si unit for velocity is m s. velocity is a vector and thus has a direction. instantaneous velocity →v v → is the velocity at a specific instant or the average velocity for an infinitesimal interval.

A position time graph—figure 2.3 • a position time graph (an x t graph) shows the particle’s position x as a function of time t. • the average x velocity is the slope of a line connecting the corresponding points on an x t graph. The average speed is 12 km h. the displacement for the round trip is zero, since there was no net change in position. thus the average velocity is zero. graphing. another way of visualizing the motion of an object is to use a graph. a plot of position or of velocity as a function of time can be very useful.
