10 Questions
What is the formula to calculate speed?
Distance / Time
If Clara took 200 seconds to run 800 meters instead of 260 seconds, what impact would it have on her speed?
Her speed would increase
How can you tell from a speed vs. time graph if an object is accelerating?
The slope of the line is positive
What does a negative acceleration represent on a speed vs. time graph?
Slowing down
If Clara's speed vs. time graph is a straight, horizontal line, what can be said about her motion?
She is moving at a constant speed
What does a positive slope on a speed vs. time graph indicate?
The object is accelerating.
How is acceleration represented on a speed vs. time graph?
Positive slope
If a line on a speed vs. time graph is steep, what does it indicate?
Larger acceleration
What does a negative slope on a speed vs. time graph signify?
Deceleration
How can you tell if an object has a larger acceleration from a speed vs. time graph?
The line is steeper.
