time graphs, such diagrams provide a snapshot of all the kinematic variables involved in the motion.Ĭertainly, you learned in math class, the slope of a function, in the x-y plane, is defined as a change in the vertical axis over a change in the horizontal axis or in math language \[\text$, the car starts to slow down its velocity for the next 0.5 seconds to the final velocity of 2 m/s, still moving in the positive $x$-axis.Įxample (4): Two cars are moving along a straight path with the following velocity vs.
Therefore, a velocity-time graph is nothing except the velocity of a moving body at any instant of time whose vertical axis has SI units of m/s. If you put these instantaneous velocities on a vertical axis, called velocity, and time on the horizontal axis, you would arrive at a so-called velocity-versus-time graph. Velocity-Time Graphs: IntroductionĬonsider a moving object so that at any instant of time you have its velocity (instant velocity). For example, if the acceleration is zero, then the velocity-time graph is a horizontal line (i.e., the slope is zero). In this article, we want to learn about these topics in detail, with some solved examples. As discussed in the previous part of Lesson 4, the shape of a velocity versus time graph reveals pertinent information about an object's acceleration. The slope of velocity-time graphs gives us average and instantaneous acceleration, The area under v-t graphs represents the displacement and distance traveled, Moments when the graph intersects the time axis, indicating turning points. time graphs gives us valuable information about the motion of a moving object.
