A student investigates the stretching of a spring in a physics laboratory.
The spring constant (kkk) of the spring is 25 N/m.
The spring is stretched so that its extension is 0.080 m.
Calculate the force applied to stretch the spring.
Use the equation:
force=spring constant×extension \text{force} = \text{spring constant} \times \text{extension} force=spring constant×extension23 exam-style questions on Edexcel GCSE Physics 15.1 Forces and springs. Each one has a worked solution and a mark scheme showing where the marks go.
