Velocity-Time Graphs. Sketch velocity vs. time graphs corresponding to the following descriptions of the motion of an object. The object is moving away from the origin at a constant (steady) speed. The object is standing still. The object moves toward the origin at a steady speed for 10s, then stands still for 10 s.
When acceleration is negative, the velocity-time graph should have a negative slope and the displacement-time graph should bend downward. When acceleration is zero, all three graphs should lie on the horizontal axis.
It’s designed to help beginning students differentiate velocity vs. time graphs from position vs. time graphs, and also to promote understanding of multiple frames of reference in analyzing an object's motion.
Real-life scenarios: Links graph features to actual examples of motion. Varied problems: Offers practice for building student confidence. Printable PDF: Great for lessons, helping with homework, or as revision notes.
If the line is horizontal, as it is between 4 and 7 seconds, velocity is constant and acceleration is zero. If the line slopes downward, like the line between 7 and 10 seconds, velocity is decreasing and acceleration is negative. Negative acceleration is called deceleration.
Explain what is “constant” when an object is moving with a constant velocity and how an object with a negative constant velocity is moving. Justify the explanation by constructing sketches of motion diagrams and using the shape of position and instantaneous velocity versus time graphs.
This collection of pages comprise worksheets in PDF format that developmentally target key concepts and mathematics commonly covered in a high school physics curriculum.
