  3. Question 33

    3 marks · Easy

    Rubber bands and metal springs behave differently when stretched. Read the statements below and answer the questions.

    (a)

    Describe how the force-extension graphs differ for a rubber band and a metal spring.

  4. Question 34

    2 marks · Easy

    A spring is 12.0 cm long without any load. A force of 5.0 N extends it to 13.5 cm. Calculate the spring's extension produced by this force. Give your answer in cm.

  7. Question 37

    3 marks · Normal

    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)

    Calculate the extension of the wire.

    [1 mark]
    (b)

    If the extension is proportional to the force for this wire, what would its length be when a 25 N force is applied?

  8. Question 38

    3 marks · Normal

    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)

    Explain how the force-extension graph for a rubber band would look different to the graph for a metal spring.

    [2 marks]
    (b)

    Give one reason why a rubber band does not obey Hooke’s law.

  9. Question 39

    3 marks · Normal

    A student is asked to describe the elastic behaviour of different materials.

    (a)

    What does it mean if a material behaves elastically?

    [1 mark]
    (b)

    Give an example of a material that shows elastic behaviour and one that shows plastic behaviour.

  10. Question 40

    4 marks · Normal

    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)

    Describe two ways the student can ensure the measurements of the wire's extension are accurate in this investigation.

    [2 marks]
    (b)

    Explain why the spring or wire should not be stretched beyond its elastic limit during this experiment.
