Speed vs. Time Graphs

What does a Speed v. Time graph show? Shows how the speed (or velocity) of an object is changing over a given period of time.

What does a horizontal line mean? A horizontal line means that the object is moving at a constant speed. Draw the distance v. time graph as well!

What does a sloped line mean? A sloped line means that the objects speed is changing over time, or accelerating. A negative slope means the object is decelerating, or slowing down. Draw the distance v. time graph as well!

What is slope equal to? The slope of the line is equal to the acceleration of the object. Which object is the image to the right has the greatest acceleration?

What if my graph is in the negative quadrant? This means that the object is coming back to the origin.

How do I calculate the distance traveled? The distance traveled is equal to the area under the curve. What was the distance traveled from this graph?

Summary Write a two to three sentence summary of your notes.

Left Side Activity Then draw the appropriate distance v. time graph to go with this speed v. time graph.
