What do particles and antiparticles have in common?
Same charge
Same mass
Same weight
What do you get when energy is converted into mass?
Equal amounts of matter and antimatter
6 protons, 7 neutrons
Neutrinos
Pair production is when a particle and an antiparticle meet, they then covert into two gamma photons which go off in opposite direction
Why are particle tracks usually curved?
Because the particles will be travelling at high speeds
Because there is usually more than one particle track
Because there's usually a magnetic field present
Which of these are made up of a particle and an antiparticle?
Baryons
Leptons
Mesons
Which of these are a correct particle and antiparticle pair?
Proton and baryon
Neutron and proton
Neutron and neutrino
Neutrino and antineutrino
Proton and antipositron
