A student carried out an investigation to determine the spring constant of a spring.
The diagram below shows the spring before and after a mass was hung from its end.
What is the extension of the spring?
- 4.5 cm4.5\text{ cm}4.5 cm
- 15.0 cm15.0\text{ cm}15.0 cm
- 19.5 cm19.5\text{ cm}19.5 cm
Give one safety precaution the student should take during this investigation.
The student hung a mass of 0.120 kg0.120\text{ kg}0.120 kg from the spring. Using a gravitational field strength of 9.8 N/kg9.8\text{ N/kg}9.8 N/kg, calculate the weight of the mass.
Use the equation: weight=mass×gravitational field strength\text{weight} = \text{mass} \times \text{gravitational field strength}weight=mass×gravitational field strength
Which of the following descriptions best represents the graph of the relationship between force applied and extension for a spring behaving elastically?
- A straight line starting from the origin (both extension and force starting at zero and increasing proportionally)
- A straight line starting above the origin on the vertical axis
- A horizontal line showing a constant extension
A force of 4.5 N4.5\text{ N}4.5 N was applied to a different spring. The extension of this spring was 0.090 m0.090\text{ m}0.090 m.
Calculate the spring constant of this spring.
Use the equation: spring constant=forceextension\text{spring constant} = \frac{\text{force}}{\text{extension}}spring constant=extensionforce
Forces and their interactions Questions
Practise AQA GCSE Physics Forces and their interactions with exam-style questions for Foundation and Higher tier. 13 questions covering Scalar and vector quantities, Contact and non-contact forces, Gravity, and Resultant forces, matched to the AQA GCSE Physics (8463) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
