Question 11
2 marks · Normal
Answer and see the solution →A box is pulled to the right with a force of 15 N and to the left with a force of 9 N. What is the resultant force acting on the box? State the size and the direction.
Question 12
3 marks · Normal
Answer and see the solution →Explain why friction is essential for a person to walk on the ground. What would happen if there were no friction between your shoes and the surface?
Question 13
3 marks · Normal
Answer and see the solution →A toy boat floats on a lake and is pulled forwards by a string with a force of 5 N. At the same time, water resistance acts on the boat with a force of 3 N in the opposite direction.
(a)[1 mark]Draw a labelled diagram showing all the forces acting on the boat. Indicate the directions clearly.
(b)[2 marks]Calculate the resultant force acting on the boat. State its direction.
Question 14

Answer and check →Which of the following is not a type of force that can act on an object?
- A.Gravity
- B.Magnetism
- C.Temperature
- D.Upthrust
Question 15

Answer and see the solution →A cyclist is moving at a steady speed along a straight road.
(a)[1 mark]Name the two horizontal forces acting on the cyclist.
(b)[2 marks]Explain, using ideas about balanced forces, why the cyclist moves at a constant speed.
Question 16

Answer and see the solution →A metal wire is stretched by attaching weights. The original length of the wire is 50.0 cm. With a 10 N force, the length becomes 50.8 cm.
(a)[1 mark]Calculate the extension of the wire.
(b)[2 marks]If the extension is proportional to the force for this wire, what would its length be when a 25 N force is applied?
Question 17
3 marks · Normal
Answer and see the solution →Rubber bands are often used to hold objects together. When you stretch a rubber band, you notice that the extension does not increase evenly as you add more force.
(a)[2 marks]Explain how the force-extension graph for a rubber band would look different to the graph for a metal spring.
(b)[1 mark]Give one reason why a rubber band does not obey Hooke’s law.
Question 18
3 marks · Normal
Answer and see the solution →A student is asked to describe the elastic behaviour of different materials.
(a)[1 mark]What does it mean if a material behaves elastically?
(b)[2 marks]Give an example of a material that shows elastic behaviour and one that shows plastic behaviour.
Question 19
4 marks · Normal
Answer and see the solution →A student investigates how extension varies with force for a metal wire. Their setup uses a half-metre rule, clamp stand, and a set square to improve measurement accuracy.
(a)[2 marks]Describe two ways the student can ensure the measurements of the wire's extension are accurate in this investigation.
(b)[2 marks]Explain why the spring or wire should not be stretched beyond its elastic limit during this experiment.
Question 20
2 marks · Normal
Answer and see the solution →A spring has an original length of 14.6 cm. When a force of 3.5 N is applied, the length of the spring increases to 16.1 cm. Calculate the extension of the spring produced by the force. Give your answer in centimetres.
