Mathematics for IGCSE & O level - Graphs In Practical Situations (Section 3 - No. 35)
Which of the following statements about speed-time graphs is/are correct?
The gradient of the graph at a point gives the acceleration at that time.
The area under the graph gives the total distance traveled during the time interval.
A horizontal line indicates constant speed.
The speed is always increasing over time.
Explication
The gradient gives acceleration, the area under gives total distance, and a horizontal line indicates constant speed. The speed isn't always increasing.
