Understand this objective

Short explanation

In the subtopic Hooke's law and spring constant, this learning objective focuses on use the equation force = spring constant x extension. For AQA GCSE Physics 8463 Unit 4.5 Forces, keep the explanation inside Hooke's law and spring constant and Forces and elasticity. Approved keywords for this objective include force, extension, and spring constant. A strong answer separates scalar and vector quantities, uses correct units where quantities are involved, and links the physical reasoning back to use the equation force = spring constant x extension. This is not a generic revision point: it is specifically about Hooke's law and spring constant, Forces and elasticity, and the approved wording of the learning objective.

Common Mistake in Hooke's Law: Remember that the spring constant (k) is a measure of stiffness and should be used as a multiplier in the equation F = k x e, where F is the force and e is the extension.
