Question
A car travels with a constant velocity of 20 m/s for 5 seconds. Calculate the distance travelled by the car during this time Explain your answer using Velocity-time graphs and velocity-time graph.
Answer
100
Explanation
A strong answer should address calculate distance travelled from the area under a velocity-time graph directly. Use the context of Velocity-time graphs within Forces and motion, then state the relevant forces or motion reasoning with units where needed. The answer is correct when it names the key physics quantity, keeps distance and displacement distinct, and links the conclusion back to the approved learning objective.
Common mistake
Misunderstanding Area Under Graph
Students often confuse the area under a velocity-time graph with speed instead of distance.
Remind students that the area under the graph represents distance travelled, not speed. Emphasize the relationship between velocity and distance in this context.
