Spec 0625
Revise CIE IGCSE Physics 1.5.1b Load–extension graphs and the spring constant with the question bank and revision guides.
Sketch, plot and interpret load–extension graphs for an elastic solid and describe the associated experimental procedures • Supplement: Define the spring constant as force per unit extension; recall and use the equation k = F / x • Supplement: Define and use the term ‘limit of proportionality’ for a load–extension graph and identify this point on the graph (an understanding of the elastic limit is not required)
