Included in these notes are the key definitions (e.g. momentum, work done) as well as the differences between vectors and scalars, conditions for forces to be in equilibrium, and the principle of moments. The centre of mass for a body is also defined. The constant acceleration equations (suvat) are given and the motion of a body in free fall is explored. Furthermore, the rules and assumptions for projectile motion are also given. In addition all 3 of Newton's laws of motion are explained as we...

Included in these notes are the key definitions (e.g. emf, resistivity) as well as the explanations for how current voltage and resistance vary with each other in components such as diodes, filament lamps, and thermistors. A description of the resistivity is given as well as how temperature affects the resistance of a metal. The meaning of a superconductor is given as well as some of its uses. In addition, the rules and differences for calculating current, voltage, and resistance for series and ...

Included in these notes are the key definitions (e.g. Young's modulus, damping) as well as the equations and explanations for how the density is measured in different states(e.g. regular solid, irregular solid, liquid). Hooke's law and the limit of proportionality are also defined as well as the transfer between elastic potential and kinetic in a spring. An explanation of tensile stress and strain and the equation linking these to Young's Modulus is also given. The difference between a britt...

Included in these notes are the key definitions (e.g. Coherence, phase difference) as well as differences between progressive and stationary waves and longitudinal and transverse waves. There is also a detailed explanation of what it means for a wave to be polarised and some of its applications including polarised sunglasses and polarised TV and radio signals. In addition, there is a description of superposition including the difference between constructive and destructive interference. The expe...

Included in these notes are a summary of protons neutrons and electrons and a definition for the specific charge of a particle. There is also an explanation for how the different forces in the nucleus ensure that it remains stable and how if these forces were affected the nucleus may become unstable which leads to decay (alpha, beta, and gamma are all explained). There is also a detailed description of how light can exist in small packets known as photons. The difference between a particle and ...
