Go to Moments, Levers & GearsWhat is Forces & Elasticity?
Elasticity is the ability of a material to return to its original shape after being stretched or compressed. Hooke's Law states that the extension of a spring is directly proportional to the force applied, up to a certain point called the limit of proportionality. Beyond this point, the material is permanently deformed (inelastic deformation).
Board notes: Covered by all major boards (AQA, Edexcel, OCR). Higher Tier students will be expected to perform calculations using Hooke's Law and understand the concept of work done in stretching a spring.
Step-by-step explanationWorked example
A spring has a spring constant of 20 N/m. What force is needed to stretch it by 10 cm? Solution: First, convert the extension to metres: 10 cm = 0.1 m. Then use Hooke's Law: Force = Spring Constant x Extension (F=ke). F = 20 N/m x 0.1 m = 2 N.
Mini lesson for Forces & Elasticity
1. Understand the core idea
Elasticity is the ability of a material to return to its original shape after being stretched or compressed. Hooke's Law states that the extension of a spring is directly proportional to the force applied, up to a certain point called the limit of proportionality.
Can you explain Forces & Elasticity without copying the notes?
2. Turn it into marks
A spring has a spring constant of 20 N/m. What force is needed to stretch it by 10 cm?
Underline the method, evidence, or command-word move that would earn credit in GCSE Forces.
3. Fix the likely mark leak
Watch for this mistake: Assuming Hooke's Law applies for any amount of force. It only applies up to the limit of proportionality.
Write one correction rule before doing another practice question.

Forces & Elasticity practice questions
These are original StudyVector questions for revision practice. They are not official exam-board questions.
Question 1
In one GCSE sentence, explain what Forces & Elasticity is testing.
Answer: Elasticity is the ability of a material to return to its original shape after being stretched or compressed. Hooke's Law states that the extension of a spring is directly proportional to the force applied, up to a certain point called the limit of proportionality.
Mark focus: Precise definition and topic focus.
Question 2
A Forces & Elasticity question uses an unfamiliar context. What should the answer do before adding detail?
Answer: It should name the process, variable, equation, particle model, or evidence being tested, then explain the result using precise scientific vocabulary.
Mark focus: Method selection and command-word control.
Question 3
A student makes this mistake: "Assuming Hooke's Law applies for any amount of force. It only applies up to the limit of proportionality." What should their next repair task be?
Answer: Do one Forces & Elasticity question and review the mistake type.
Mark focus: Error correction and next-step practice.

Common mistake
What mistake should you avoid in Forces & Elasticity?
Assuming Hooke's Law applies for any amount of force. It only applies up to the limit of proportionality.

Exam board
How should you use board notes for Forces & Elasticity?
Covered by all major boards (AQA, Edexcel, OCR). Higher Tier students will be expected to perform calculations using Hooke's Law and understand the concept of work done in stretching a spring.
Common mistakes
- 1Assuming Hooke's Law applies for any amount of force. It only applies up to the limit of proportionality.
- 2Confusing elastic and inelastic deformation. Elastic deformation is temporary; the object returns to its original shape. Inelastic (or plastic) deformation is permanent.
- 3Plotting the graph of force against extension incorrectly. Force should be on the y-axis and extension on the x-axis. The gradient of the straight-line part is the spring constant.

Frequently asked questions
What is Hooke's Law?
Hooke's Law states that the force needed to stretch or compress a spring by some distance is directly proportional to that distance. The equation is F = ke, where k is the spring constant.
What is the elastic limit?
The elastic limit is the point beyond which a material is permanently stretched. If you stretch it past this point, it will not return to its original length when the force is removed.
