Acceleration:rate of change of velocity with respect to time
Ampere: The current which when flowing in two straight parallel conductors of infinite length, placed one meter apart in a vacuum, would
produce a force of 2×10-7 newtons per metre of length.
Amplitude: The distance top (or bottom) of a wave to the middle of the wave.
Angular Speed/Velocity: The rate of change of angle with respect to time
Anode: The positive electrode in a cell or solution.
Atomic Number: The number of protons in the nucleus.
Becquerel:SI unit for radioactive decay/activity, Becquerel(Bq) = 1
disintegration per second.
Capacitance: The ability of a material to store electric charge.
Cathode: The negative electrode in a cell or solution. Centre of curvature
Centripetal acceleration: The acceleration towards the centre of a body moving in a circle
Centripetal force: The force towards the centre needed to need a body moving in a circle.
Chain reaction: A self-sustaining nuclear reaction, the products of which
need the reaction going.
Coherent: Light is coherent if the waves are in phase or have a
constant phase relationship.
Conductor: A material capable of carrying an electric charge.
Constructive interference: Crests from one source always meet the crest from another
source.
Converging/convex lens: Lens capable of bring to a point a beam of light passing through
it.
Coulomb: SI unit of electric charge, 1 coulomb(C) = 1 ampere per second.
CoupleTwo equal and opposite parallel, but not linear forces acting
on a body.
Critical angle: The minimum angle of incidence at which total internal reflection
occurs.
Doping: Adding small amounts of impurity to a semiconductor to make
it N or P type.Doping
Adding small amounts of impurity to a semiconductor to make
it N or P type.
Doppler effect
The apparent change in frequency of sound or radiation
due to the relative motion of the source and observer.
Eddy currents
Induced electric currents in conductors due to changing magnetic
flux.
Electric field strength
The force per unit charge that a positive charge would experience
if placed at that point in the field.
Electromagnetic induction
Whenever the magnetic field passing through a coil changes
this causes an electromagnetic force in the coil.
Electromotive Force
The energy given to each coulomb of charge as it goes through
a battery or generator.
Farad
SI unit of capacitance, 1F = 1 coulomb across potential difference
of 1 volt.
Focal Length
The distance for the focal point to the mirror.
Force
Anything that causes the velocity of an object to change.
Forward bias
When a diode is connected to a battery so that current flows.
Frequency
The number of oscillation or cycles per second.
Friction
The force that opposes the sliding of surfaces in contact.
Fundamental frequency
The lowest possible vibration of a stationary wave.
Half life
The time taken for half of the undecayed atoms undergo a decay
in a radioactive isotope.
Harmonic
A wave whose vibration is a whole multiple of the fundamental
frequency.
Heat
Energy transfer from one place to another due to a temperature
difference.
Hertz
Measure of frequency, 1 hertz is one cycle per second.
Interference
The addition or combination of waves, it can be either destructive
or constructive.
Isotope
Atoms of that same element that have different mass numbers.
They have different amounts of neutrons.
