EXAMPLE 2.1 – Interpreting graphs. Another way to represent positions and displacements is to graph the position as a function of time, as in Figure 2.4. This graph could represent your motion along a sidewalk. What happens at a time of t = 40 s? Draw a diagram similar to that in Figure 2.3, to show your motion along the sidewalk.
EXAMPLE 2.2A – Average velocity and average speed Consider Figure 2.6, the graph of position-versus-time we looked at in the previous section. Over the 50-second interval, find: (a) the average velocity, and (b) the average speed. SOLUTION (a) Applying Equation 2.2, we find that the average velocity is:.

Distance in Graphs This lecture introduces the notion of a weighted graph and explains how some choices of weights permit us to define a notion of distance in a graph.
Answer: 1) 135 km, 85km forward 2) 0 m, 6 m • Distance ( ): the separation between two points. Ex, the length of an object. Usually measures in _____. No _____ needed ex) • Displacement ( or ): A measure of the change in position. Needs _____ Δd = final position – initial position.
Introduction to Position-Time Graphs Position-Time Graphs tell you where an object is located over a period of time. The slope of the graph tells you how fast the object is moving. The sign of the slope indicates direction of motion. What would a graph look like if an object is… Moving away from 0 meters Stopped Moving towards 0 meters.
How far would you drive? The distance an object moves is the length of the path between its initial position and its final position. The distance you drive to your friend's house depends on your path. As shown in Figure 2.5, distance is different from the length of a straight line between two points. The distance you drive to your friend's ...
