Rutherford's Gold Foil Experiment Simulation

 This is a sim developed for NCEA 2 Physics AS 91172 "Demonstrate understanding of atomic and nuclear physics".


Note: this sim is for illustration purposes only! It is WAAAAAAY out of scale and vastly over-represents the proportion of alpha particles that were deflected or bounced back!

Level 2 Physics AS91172: "Demonstrate Understanding of Atomic and Nuclear Physics"

 Here's the series of videos I've done for nuclear physics.


The first one deals with Rutherford's famous gold foil experiment and models of the atom that you'll need to identify and explain in your assessment. 


Part 2 deals with radiation, radioactive decay types that you need to be able to explain (alpha, beta+, beta- and theta decay) and half-lives. 


In part 3 we discuss nuclear fusion, fission and nuclear power.
