Worked Solution & Example Answer:The graph in Figure 5 shows how the velocity of a car changes with time - Edexcel - GCSE Physics - Question 3 - 2023 - Paper 1
Step 1
Which part of the graph shows when the car has constant velocity?
Answer
The car exhibits constant velocity during the interval PQ, where the velocity remains unchanged at 10 m/s. This portion of the graph is represented by a straight horizontal line, indicating no change in speed over that time period.
Step 2
Which part of the graph shows when the car has the greatest acceleration?
Answer
The greatest acceleration occurs during the segment QR. In this part of the graph, the velocity increases from 10 m/s to 20 m/s over a time interval, indicating a rapid change in speed and thus the highest acceleration.
