Lots of people are asking me about the answers to these North Ayrshire revision check tests. Can I also recommend you pop across to the Learning Outcome Questions, which have fully worked answer. Click on the links below. No cheating though!

Thanks to those in North Ayrshire who provided these excellent questions for you to get your teeth into. I’ll post the answers as password protected to protect those students and staff who are giving these for homework! They’re in the old order, so you’ll have to search through for the right section.
ENJOY!
| TERM | DEFINITION (140 characters or less) |
|---|---|
| #4 FUNDAMENTAL FORCES | Fundamental forces: interactions that cannot be reduced. There are 4 types. The forces keep all matter together in the universe. |
| #ANNIHALATE | Process in which a particle and antiparticle unite, annihilate each other, and produce 1 or more photons. Energy and momentum are conserved. |
| #ANTIMATTER | Matter consisting of elementary particles which are the antiparticles of those making up normal matter. |
| #BARYON | A subatomic particle which contains 3 quarks. Baryons are hadrons. |
| #BOSON | A subatomic particle, such as a photon, which has zero or integral spin. All the force carrier particles are bosons. |
| #COLOUR | Particle has 3 apparently identical quarks but have different properties categorised by colour to satisfy Pauli Exclusion Principle |
| #ELECTROMAGNETIC FORCE | 1 of 4 fundamental forces. influencing electrically charged particles. Responsible for electricity, magnetism and light and holds p+ and e- together |
| #ELECTROMAGNETIC FORCE | Affects electrically charged particles. Responsible for electricity, magnetism, & light;holds e- and p+ in atoms; allows atoms to bond to form molecules. Causes objects to be solid |
| #EXCHANGE PARTICLE | Particle that carries forces for strong force – gluon, weak force – W and Z bosons, electromagnetic – photon and gravitational – graviton. |
| #FERMION | Matter particles e.g. proton, neutron and electron. Can be hadrons or leptons |
| #GLUON | A supposed massless subatomic particle believed to transmit the force binding quarks together in a hadron. They mediate the strong force. |
| #GRAVITATIONAL FORCE | A force that attracts any object with mass. |
| #HADRON | A particle made of quarks. Two families: baryons – made of 3 quarks & mesons – made of 1 quark & 1 antiquark. Protons & neutrons are baryons |
| #HIGGS BOSON | fundamental particle, used by Higgs Field, to interact with other particles two give them m, causes particles to slow therefore cannot reach c due to m. |
| #LEPTON | Elementary particles, the basic building blocks of matter. Six leptons are in present structure. Varieties are called flavours. |
| #MESON | Are intermediate mass particles that are made of a quark- antiquark pair. Mesons are bosons and hadrons. |
| #MUON | A particle similar to the electron, with an electric charge of −1 e and a spin of 1/2, but with a much greater mass. It is classified as a lepton. |
| #NEUTRINO | A neutral subatomic particle. Mass close to zero. Half-integral spin.Rarely reacts with normal matter. 3 types of neutrino are electron, muon and tau. |
| #POSITRON | Positron= antielectron =the antiparticle of the electron has an electric charge is +1 e, a spin of 1/2, same mass as an electron. |
| #QUARK | Quark: a fundamental particle. Quarks combine to form composite particles called hadrons. The most stable hadrons are protons and neutrons. |
| #SPIN | All particles have spin. Can be up or down & has a fixed value which depends on the type of particle. Particles can be right or left handed |
| #STANDARD MODEL | Theory concerning electromagnetic, gravitational, strong and weak nuclear interactions and classifying all known subatomic particles. |
| #STRONG FORCE | Binds quarks together to make subatomic particles e.g.protons and neutrons. Holds together the atomic nucleus. Causes interactions between particles that have quarks. |
| #WEAK FORCE | A force that plays a role in things falling apart, or decaying. |
