Question
- A. By finding the area under the graph.
- B. By measuring the gradient of the graph.
- C. By counting the number of points on the graph.
- D. By finding the total distance travelled.
Answer
By measuring the gradient of the graph.
Explanation
The speed of an object can be calculated by measuring the gradient of the distance-time graph, which represents the change in distance over time.
Common mistake
Misinterpreting Distance-Time Graphs
Students often confuse a horizontal line on a distance-time graph as indicating motion rather than being stationary.
Remember that a horizontal line indicates no change in distance over time, meaning the object is stationary.
