When the velocity is constant, the velocity-time graph, with Y-axis denoting velocity and the X-axis denoting time, will be like: As the graph shows, the velocity is constant (c) throughout the interval. No particles of matter how much the time changes, the velocity will be c at every instant.

Consider a car moving with a constant, rightward (+) velocity - say of +10 m/s. As learned in an earlier lesson, a car moving with a constant velocity is a car with zero acceleration. If the velocity-time data for such a car were graphed, then the resulting graph would look like the graph at the right. Note that a motion described as a constant, po...
The shapes of the velocity vs. time graphs for these two basic types of motion - constant velocity motion and accelerated motion (i.e., changing velocity) - reveal an important principle. The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero,...
The answers to these questions hinge on one's ability to read a graph. Since the graph is a velocity-time graph, the velocity would be positive whenever the line lies in the positive region (above the x-axis) of the graph. Similarly, the velocity would be negative whenever the line lies in the negative region (below the x-axis) of the graph. As lea...
Now how can one tell if the object is speeding up or slowing down? Speeding up means that the magnitude (or numerical value) of the velocity is getting large. For instance, an object with a velocity changing from +3 m/s to + 9 m/s is speeding up. Similarly, an object with a velocity changing from -3 m/s to -9 m/s is also speeding up. In each case, ...

(include all that are true): 1. moving in the positive direction. 2. moving with a constant velocity. 3. moving with a negative velocity. 4. slowing down. 5. changing directions. 6. speeding up. 7. moving with a positive acceleration. 8. moving with a co...
Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or ...
The velocity-time data for this motion show that the car has an acceleration value of 10 m/s/s. (In Lesson 6, we will learn how to relate position-time data such as that in the diagram above to an acceleration value.) The graph of this velocity-time data would look like the graph below.
Mar 31, 2022 · Describing Motion with Velocity vs Time Graphs. Velocity-time graphs are relatively similar to position-time graphs, and just as important in the study of motion graphs. We still have our time in seconds along the x-axis, but now we have our velocity in meters per second along the y-axis. Let’s consider the velocity-time graph below.
Aug 7, 2024 · A velocity time graph, or velocity-time graph, shows how the velocity of a moving object varies with time. Velocity-time refers to the fact that velocity is plotted against time on the graph; The red line represents an object with increasing velocity; The green line represents an object with decreasing velocity
