This is a pdf version of a deck I made on a flashcard tool called Anki, as Stuvia do not take the original file type. Anki is a very powerful tool that helped me get 7 9s and 2 8s at GSCEs and has helped me massively during my A Levels thus far. Using this alongside past paper questions is guarant...
Physics A Level
particle physics is about...
the fundamental properties of matter, radiation and energy
protons and neutrons consist of smaller
particles called...
quarks
what are leptons
a family of particles
the building blocks of matter are...
quarks and leptons
what are the wave packets of electromagnetic
radiation called?
photons
the theory that energy is in these lumps
(quanta) instead of being evenly spread, makes
up part of the...
quantum theory
what is a nucleon
a proton or a neutron in the nucleus
,SI unit for charge?
Coulombs (C)
SI unit for mass
Kilogram (kg)
mass of proton
1.67 x 10 to the power of -27
mass of proton relative to proton
1
mass of neutron relative to proton
1
what are isotopes
isotopes are atoms with the same number of protons and different numbers of
neutrons.
the nucelon number is also known as the...
mass number
the atomic number is labelled as
Z
,units for specific charge?
coulombs per kilogram ( C kg-1)
units for overall charge
C (coulombs)
out of all the particles, electrons have the
highest...
charge to mass ratio ( Specific charge)
specific charge is also known as
charge to mass ratio
specific in physics means
per unit mass
to work out the charge of a positive ion for
specific charge...
you multiply ion number by charge of electron.
eg.) Mg 2+ , charge of ion is 2 x -1.60 x 10-19 C
to work out the mass of a positive ion for
specific charge....
calculate mass of the atom before it became an ion
, size of electrostatic repulsion increases when 2
protons...
are pushed closer together
strong force is carried by a
gluon
what is a gluon
a type of boson
what do bosons have
a very short half life
what is a femtometre
a quadrillionth of a metre, 10 to the power of -15m
symbol of nucelon/mass number
A
the electrostatic force between two charged
particles decreases when..
the range increases
what happens at separations between nucleons
below 0.5fm
repulsive force acts to prevent neutrons and protons being pushed into each
other
