Hooke's Law (AQA GCSE Physics Combined Science): Flashcards

Extension ∝ force (within limit of proportionality)

Point where Hooke's Law stops applying

Max stretch where material returns to original shape

Material becomes permanently deformed

$F = kx$

Force applied (Newtons)

Spring constant ($Nm^{-1}$)

Extension (metres)

Elastic region, follows Hooke's Law

Spring constant ($k$)

Plastic behaviour, doesn't follow Hooke's Law

Linear only, snaps instead of stretching

Limit of proportionality
