Unit 1 Definitions

HideShow resource information
Isotope
Atoms with the same number of protons but different number of neutrons
1 of 11
Pair production
Two protons fired at each other at high speed with a lot of energy at the point of impact - the energy is converted into a proton and an antiproton
2 of 11
Quark confinement
It is impossible to get a quark on its own
3 of 11
The Photoelectric effect
The shining of light on a metallic surface which releases electrons
4 of 11
Wave-Particle Duality
Particles can have wave-like properties and waves can have particle-like properties
5 of 11
Current
Rate of flow of charge
6 of 11
1 Coulomb
The amount of charge that passes in 1 second when the current is 1 ampere
7 of 11
Potential Difference
Energy per unit charge
8 of 11
Ohm's Law
Provided the temperature is constant, the current through an ohmic conductor is directly proportional to the potential difference across it
9 of 11
Resistivity
The resistance of a 1m length with a 1m^2 cross sectional area
10 of 11
Power
The rate of transfer of energy
