AQA A Level PHYSICS PAPER 2
May 2024 Exam Questions and
Answers
Gravitational Field - Answer>> A region in which an object that
has mass experiences a force
Field Lines - Answer>> Arrows which indicate the direction and
relative strength of a field. Arrows show the way in which a rest
mass would experience the force of attraction.
Equipotentials - Answer>> Lines drawn to indicate points of
equal potential. Cross field lines at 90 degrees
Newton's Law of Gravitation - Answer>> Every particle in the
universe attracts every other particle with a force that is directly
proportional to the product of their masses and inversely
proportional to the square of the distance between their centre's
F ~~ Mm/r^2
Gravitational field strength - Answer>> The force acting on a
body per unit mass
Gravitational Potential Energy - Answer>> Potential energy is
the work done in moving an object with mass from Infinity to that
point in the field
E=-gMm/r for radial field E=mg•dh (Scalar)
Absolute Gravitational potential - Answer>> The absolute
gravitational potential at a point is the work done per unit mass in
moving a body from Infinity to that point in the gravitational field
V=-Gm/r (scalar)
