• Question 5Oct/Nov 2023, paper 11Multiple choice1 markHas a diagram

  The diagram shows how the length of a spring changes when a load of $10\text{ N}$ is suspended from it. The $10\text{ N}$ load is replaced by a $20\text{ N}$ load. What is the new length of the spring?

• Question 7May/June 2024, paper 11Multiple choice1 mark

  An unstretched spring of length 15.0 cm stretches by 4.0 cm when a mass of weight 6.0 N is suspended from it. The spring does not exceed the limit of proportionality. What is the total length of the spring when the weight of the suspended mass is 3.0 N?

• Question 4Oct/Nov 2023, paper 41Essay6 marksHas a diagram

  A student investigates the factors affecting the bend angle $\theta$ of a metal strip. The student places a thin, straight metal strip on two supports and attaches a mass of weight $W$ to the middle of the strip. The metal strip bends as shown in Fig. 4.1.

• Question 1Oct/Nov 2023, paper 42Structured10 marksHas a diagram

  A student measures the spring constant $k$ of a spring using two different methods. The spring constant $k$ of a spring is a measure of the stiffness of the spring. The larger the spring constant $k$, the more difficult the spring is to stretch.
