A level Physics Paper 2 Exam Questions And
Answers Latest Update 2025
Hooke's Law -
correct answer ✅∆F = k∆x
where k is the stiffness of the object
Stress -
correct answer ✅σ=F/A
where F is force and A is cross sectional area
Strain -
correct answer ✅ε=∆x/x
where x is the original length of the material and ∆x is the
extension
Young Modulus -
correct answer ✅Stress/Strain
,A level Physics Paper 2 Exam Questions And
Answers Latest Update 2025
Tensile stress/strain -
correct answer ✅Causes the length of the material to increase, the
forces act away from the center
Compressive stress/strain -
correct answer ✅Causes the length of the material to decrease,
the forces act towards the center
Force Extension graph -
correct answer ✅
Stress strain graph -
correct answer ✅

Answers Latest Update 2025
Stress Strain Graphs for Different Materials -
correct answer ✅Stiffer materials have a steeper gradient.
Stronger materials have a large breaking stress
Brittle materials have a very small plastic regions
Stress Strain Graph for Rubber -
correct answer ✅
Limit of Proportionality -
correct answer ✅*The point until which force and extension (or
, A level Physics Paper 2 Exam Questions And
Answers Latest Update 2025
stress and strain) are directly proportional. After this point it may
behave elastically, but they will no longer be proportional*
Elastic Limit -
correct answer ✅*The point beyond which the material is
permanently deformed, it won't return to it's original shape*
Yield Point -
correct answer ✅*Beyond this point the material suddenly
undergoes a large increase in extension (it 'gives') as the atomic
substructure is rearranged*
Breaking stress -
correct answer ✅*The value of stress in a material when it breaks*
Elastic Deformation -
correct answer ✅*Region where the material will return to its
original shape when the stress is removed*
Plastic Deformation -
correct answer ✅*Permanent deformation caused by strain when
