AQA A LEVEL PHYSICS PAPER 1 TRAINING
STUDY SHEET 2026 UPDATED QUESTIONS
AND ANSWERS
◉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
◉Principle of Moments. Answer: For an object in equilibrium, sum
of clockwise moments about a point must equal the sum of the
clockwise moments about the same point
◉Couple. Answer: A pair of equal and opposite coplanar forces that
act parallel to one anotherm
◉Moment of a Couple. Answer: The force multiplied by the
perpendicular distance between the lines of action of the forces
