Graphical Interpretation of Velocity Velocity can be determined from a position-time graph Average velocity equals the slope of the line joining the initial and final positions An object moving with a constant velocity will have a graph that is a straight line
Graphical Interpretation of Velocity ◼ Velocity can be determined from a position-time graph ◼ Average velocity equals the slope of the line joining the initial and final positions ◼ An object moving with a constant velocity will have a graph that is a straight line
Average velocity Constant The straight line t(m) indicates constant velocity 20 The slope of the line is the value 0 of the average velocity -40 10
Average Velocity, Constant ◼ The straight line indicates constant velocity ◼ The slope of the line is the value of the average velocity
