Sample cards from this deck

Definition
Electric circuits and Ohm's law: QCE Physics Unit 1 Year 11
Define Charge $q$
Charge $q$ (coulombs C). Elementary charge $e = 1.6 \times 10^{-19}$ C.
Definition
Displacement, velocity and acceleration (QCE Physics Unit 2)
Define Distance
The total length of the path travelled. Scalar.
Definition
Newton's law of universal gravitation and gravitational fields (QCE Physics Unit 3)
Define Action at a distance
The two masses pull on each other directly across empty space.
Definition
The four fundamental forces (QCE Physics Unit 4)
Define Mediator
Gluon (8 types). Massless. Carry colour charge.
Definition
Nuclear physics and radioactivity: QCE Physics Unit 1 Year 11
Define Alpha
Emit helium nucleus $^4_2$ He. Mass number drops 4, atomic number drops 2. Range: cm in air; stopped by paper.
Definition
Linear motion and Newton's laws: QCE Physics Unit 2 Year 11
Define First law (inertia)
A body at rest stays at rest, and a body in motion stays in motion at constant velocity, unless acted on by a net external force. Inertia is the resistance of mass to a change in motion, so a more massive object is harder to accelerate or stop. Seatbelts and headrests are direct applications: when a car stops suddenly, the passenger continues forward at the original velocity until a force restrains them.
Definition
Orbital motion, Kepler's third law and satellite energy (QCE Physics Unit 3)
Define First law
Planetary orbits are ellipses with the Sun at one focus. Circular orbits are the special case of zero eccentricity.
Definition
Fundamental particles and the Standard Model: QCE Physics Unit 4
Define Bosons
Bosons (force carriers, integer spin): gauge bosons and the Higgs.
Definition
Thermal physics and kinetic theory: QCE Physics Unit 1 Year 11
Define Internal energy
Internal energy is the total of all the kinetic and potential energies of the particles in a sample. It is an extensive property, so it scales with the amount of substance. A large mass of warm water can hold far more internal energy than a small mass of very hot water, which is the key distinction QCAA tests.
Definition
Newton's laws and forces (QCE Physics Unit 2)
Define First law (inertia)
An object continues in a state of rest or uniform motion in a straight line unless a net external force acts on it. A net force of zero means constant velocity (which includes being at rest).
