AQA A LEVEL PHYSICS PAPER 1
COMPREHENSIVE PAPER 2026 QUESTIONS
AND SOLUTIONS GRADED A+
◉Ultimate Tensile Stress. Answer: The maximum stress that a
material can withstand
◉Young Modulus. Answer: The ratio of stress to strain for a
particular material
◉Limit of Proportionality. Answer: The point beyond which force is
no longer proportional to extension
◉Brittle Material. Answer: Doesn't deform plastically but snaps
when the stress on it reaches a certain point
◉Brittle Fracture. Answer: When a stress applied to a brittle
material caused tiny crack at the material's surface to get bigger
until the material breaks completely
, ◉Yield Point. Answer: The point at which a material will continue to
stretch without any extra load being applied
◉Elastic Limit. Answer: The maximum amount that a material can
be stretched and still return to its original length when all force is
removed
◉Elastic Strain Energy. Answer: The energy stored in a stretched
material
◉Elastic Collision. Answer: A collision in which the total momentum
and the total kinetic energy are conserved
◉Inelastic Collision. Answer: A collision where momentum is
conserved but kinetic energy is not
◉Principle of Conservation of Energy. Answer: Energy cannot be
created or destroyed, it can be changed from one form to another,
but the total amount of energy in a closed system will not change
◉Scalar. Answer: A quantity that only has magnitude no direction
◉Vector. Answer: A quantity that has both magnitude and direction
