Therefore, the motion of any object that moves at a constant speed can be represented on a speed–time graph by a horizontal line. We can also turn this statement on its head to say that any horizontal line on a speed–time graph must represent the motion of an object that moves at a...

A straight-line distance-time graph represents motion at constant speed. In each 2-s interval, the object moves 6 m. Therefore, the average speed is v = 6 m/2 s = 3 m/s. v¯=6m2s=3m/s In this case it does not matter what time interval we choose; we always obtain v¯ =...
Example : A boy walks in a positive direction and then back again with a constant speed of 2 m/s, so he walks with a velocity of +2 m/s and then with a velocity of –2m/s. Image Distance–time graphs On a distance–time graph: ...
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. For example, for this trip to the store, the position, velocity, and speed-vs.-time graphs are displayed in Figure 4. (Note that ...
