Question 11
2 marks · Normal
Answer and see the solution →The velocity–time graph of a car shows that its velocity increases from 5 m/s to 25 m/s in 10 s. Calculate the acceleration of the car.
Question 12
2 marks · Normal
Answer and see the solution →Explain how you could use a velocity–time graph to determine whether an object is moving with uniform acceleration.
Question 13
2 marks · Normal
Answer and see the solution →A train slows from 24 m/s to rest in 30 s. Calculate its acceleration.
Question 14
3 marks · Normal
Answer and see the solution →A ball is rolled down a slope. The velocity–time graph for the ball shows a straight line with a positive gradient. Explain what this tells you about the ball’s acceleration and movement, using ideas from Galileo’s experiments.
Question 15
3 marks · Normal
Answer and see the solution →A toy car moves in a straight line. The velocity–time graph for the car is shown below:
Velocity–time graph for a toy car (a)[1 mark]Calculate the gradient of the graph.
(b)[2 marks]State what the gradient represents about the car's motion.
Question 16
2 marks · Normal
Answer and see the solution →A velocity–time graph for a moving object is curved upwards. Explain what this shape tells you about the object's acceleration.
Question 17
3 marks · Hard
Answer and see the solution →A velocity–time graph is plotted for a skateboarder moving in a straight line. The table shows the velocity of the skateboarder at certain times:
Time / s Velocity / m/s 0 2 2 10 4 18 6 26 (a)[1 mark]Plot the four points for the velocity–time data on axes. Label both axes.
(b)[2 marks]Determine the gradient of the graph and use it to find the skateboarder’s acceleration.
Question 18
3 marks · Hard
Answer and see the solution →Describe, with reference to a velocity–time graph, how you would recognise when an object is decelerating and determine how to calculate the deceleration using the graph.
