Nuclear Physics

We have just come to the end of our final Physics topic 'Nuclear Physics'. Confusingly this has lots of ideas relating to the structure of the atom which we covered in our Y11 chemistry work at the end of Y10. The difference is that chemistry is concerned with interactions between the outer electrons of atoms (e.g. in ionic and covalent bonding), whereas physics is concerned with changes in the nucleus of the atom. Chemical reactions involve changes to electrons, nuclear reactions involve changes to the nucleus.

You need to be able to describe three kinds of nuclear reaction, with symbol equations showing the atomic numbers and atomic masses of each atom and particle (alpha, beta, neutron):
Radioactive decay (alpha and beta)
Nuclear fission
Nuclear fusion

Homework is to have a go at these:

Homework - Mains Electricity revision questions

Last week we completed our look at mains electricity with calculations of:
Electrical power (Watts, W) = potential difference (Volts, V) x current (Amps, A)
and:
Energy transferred (or work done) (Joules, J) = potential difference (Volts, V) x charge transferred (Coulombs, C)

Aim to answer and mark the following questions and bring your marked work to our lesson on Friday 27th January.

P2 Physics - end of section homework resources

Section 1: Motion

We've spent the first few lessons of this term reviewing work you did with Mr Altaf at the end of last term. Make sure you can calculate distance, time, speed and acceleration using the two equations we've met, and that you understand the meaning of the slopes of distance and velocity time graphs, and the area under a velocity-time graph.

We will have a test on this on Monday 26th September - below are links to questions with answers for your homework.
