- B. By calculating the gradient of the graph
- C. By measuring the distance travelled
- D. By determining the time taken
Answer
By calculating the gradient of the graph
Explanation
The acceleration of an object can be determined by calculating the gradient (slope) of the velocity-time graph.
Common mistake
Misinterpreting Velocity-Time Graphs
Students often confuse a straight sloping line on a velocity-time graph with constant speed instead of constant acceleration.
Remind students that a straight sloping line indicates a constant change in velocity, which is defined as acceleration.
