3 cards from this section. Quick, good the night before a test.
What does a flat line on a velocity-time graph indicate?
Think about what happens to speed over time.
In a velocity-time graph, what does a rising slope represent?
How do speed and time relate when speed increases?
What does the area under a velocity-time graph represent?
What are we counting when we consider area under the graph?
True or False: A downward sloping line on a velocity-time graph indicates increasing speed.
Think about the relationship between graph slope and speed.
A cyclist travels with varying speeds shown in a velocity-time graph with segments for different speeds. If the graph shows a triangular area for acceleration and a rectangular area for uniform speed, calculate total displacement over 10 minutes.
Use height and base for area expressions.
Sketch a velocity-time graph showing a car accelerating for 5 seconds, moving at constant speed for 10 seconds, and decelerating to a stop in another 5 seconds. Calculate the total distance from your graph.
Check area formulas: triangle for acceleration, rectangle for constant speed.
