Topic 9: Motion in Fields:
The path in projectile motion is always a parabola (e.g. catching a ball). The only
forces acting in projectile motion are gravity and friction. It is moving horizontally
and
vertically at the same time but the horizontal and ve
Option G: Electromagnetic Waves:
Outline the nature of electromagnetic (EM) waves.
Oscillating electric charge produces varying
electric and magnetic fields Electromagnetic
waves are transverse, have the same speed
Oscillating (SHM) charge produces an ele
Topic 4 Oscillations and Waves:
Examples of oscillations include the swinging of a pendulum
Displacement (x) is the instantaneous distance of the moving object from its mean
position Amplitude (A) is the maximum displacement from the mean position
Frequen
Topic 6: Fields and Forces:
Newtons Law of Gravitation states that every mass in the Universe attracts all other
masses in the Universe given by F=Gm1m2/r2
Gravitational field strength is the gravitational force exerted per unit mass. g=F/m, g=GM/r2

Topic 13: Quantum Physics and Nuclear Physics:
The photoelectric effect is the phenomenon where electrons are emitted from the
surface of a metal after being exposed to light (of a particular frequency called
the threshold frequency).
Light below the thre
Topic 1: Physics and Physical Measurement:
The realm of physics:
The order of magnitude is i.e. 10x.
Range of masses (kg): 10-32 (electron) to 1052 (mass of the observable
universe) Range of lengths (m): 10-15 (diameter of proton) to 1026 (radius of
unive
7.2: Radioactive Decay:
Radioactive decay: process in which unstable atomic nucleuss loses energy by
emitting radiation in form of particles or EM waves, resulting in the
transformation of parent nuclide into daughter nuclide. Measured in Becquerels
(Bq)
Topic 11: Wave Phenomena:
Nature of standing (stationary)waves
Amplitude
Frequency
Wavelength
Phase
Energy
Standing wave
All points on the wave have
different amplitudes. The
maximum amplitude is 2A
at the antinodes. It is zero
at the nodes.
Normal (trave
Wave Properties:
In general when any wave reaches the boundary between two different media it is
partially reflected and partially transmitted. P41
The law of reflection: when a wave is reflected, the angle of incidence equals the
angle of reflection and
Outline the Schrdinger model of the hydrogen atom.
The model assumes that electrons in the atom may be
described by wave functions. The electron has an
undefined position, but the square of the amplitude
of the wave function gives the probability of findi
Topic 3 Thermal Physics:
Temperature is a scalar quantity that gives indication of the degree of hotness or
coldness of a body.
Temperature determines the direction of thermal energy transfer between two bodies
in contact; from the body at higher temperat
