This resource is a complete lesson that covers Quarks & Antiquarks for the OCR A Level Physics A course. However, it is useful for other exam boards too.
This lesson teaches the following content:
-simple quark model of hadrons in terms of up (u), down (d) and strange (s) quarks and their respective anti-quarks
-quark model of the proton (uud) and the neutron (udd)
-charges of the up (u), down (d), strange (s), anti-up (u), anti-down (d) and the anti-strange (s) quarks as fractions of the elementary charge e
-beta-minus (β-) decay; beta-plus (β+) decay
-quark confinement
-β– decay in terms of a quark model; d -> u + (β–) + v̅
-β+ decay in terms of a quark model; u -> d + (β+) + v
-balancing of quark transformation equations in terms of charge
-decay of particles in terms of the quark model.
This lesson includes:
-A full presentation including an example question with a worked solution.
-A worksheet with model answers, perfect to set as homework.
-Clear visual aids and diagrams to simplify complex concepts.
-Editable PowerPoint and Word document for easy customisation.
