- Physics
- Atoms
- Bohr Model
- Protons (+1), Neutrons (0) located at the centre in nucleus. Electrons (-1) orbit nucleus.
- Nuclear Decay
- Beta = high energy electron shot out of decaying nucleus. Charge -1. Aluminium sheet enough to stop it.
- Alpha = Helium nucleus (2 pro's, 2 neut's). Charge +2. Aluminium sheet enough to stop it
- Exponential Decay = decay rate proportional to amount of remaining material.
- Half life t1/2 such that after each time t1/2, amount of material halves.
- Radiation
- change atom composition which changes element or proporties.
- Bohr Model
- Electricity
- Ohm's Law
- I=V/R
- I = current. V=Voltage. R=Resitance
- I=V/R
- Ohm's Law
