This resource is a complete lesson that covers Particles & Antiparticles for the OCR A Level Physics A course. However, it is useful for other exam boards too. This lesson teaches the following content: -particles and antiparticles; electron–positron, proton-antiproton, neutron-antineutron and neutrino-antineutrino -particle and its corresponding antiparticle have same mass; electron and positron have opposite charge; proton and antiproton have opposite charge -classification of hadrons; proton and neutron as examples of hadrons; all hadrons are subject to both the strong nuclear force and the weak nuclear force -classification of leptons; electron and neutrino as examples of leptons; all leptons are subject to the weak nuclear force but not the strong nuclear force -Einstein’s mass–energy equation; ΔE = Δmc² -creation (i.e. pair production) and annihilation of particle–antiparticle pairs This lesson includes: -A full presentation including 3 example questions with worked solutions. -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.

This resource is a complete lesson that covers Simple Harmonic Motion for the OCR A Level Physics A course. However, it is useful for other exam boards too. This lesson teaches the following content: -displacement, amplitude, period, frequency, angular frequency and phase difference -simple harmonic motion; defining equation a =-ω²x -techniques and procedures used to determine the period/frequency of simple harmonic oscillations -solutions to the equation a = -ω²x e.g. x = Acosωt or x = Asinωt -velocity v = ± ω √ (A² - x²) hence vmax = ωA -the period of a simple harmonic oscillator is independent of its amplitude (isochronous oscillator) -graphical methods to investigate simple harmonic motion (mass of spring system). -interchange between kinetic and potential energy during simple harmonic motion -energy-displacement graphs for a simple harmonic oscillator This lesson includes: -A full presentation including 2 example questions with worked solutions. -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.
