Transverse & Longitudinal Waves In mechanical waves, particles oscillate about fixed points There are two types of wave: transverse and longitudinal The type of wave can be determined by the di...
Properties of Waves Travelling waves are defined as follows: Oscillations that transfer energy from one place to another without transferring matter Energy is transferred by the waves, but matter i...
Energy in SHM The total energy of an object oscillating with SHM is the sum of its potential energy (gravitational or elastic) and kinetic energy E = EP + EK Where: E = total energy in joules (J) E...
SHM Graphs Displacement & Velocity The displacement-time graph for an object moving with SHM is a sinusoidal curve if: The object starts to oscillate from the equilibrium position. The equilibr...
Simple Harmonic Oscillations Simple harmonic motion (SHM) is defined as follows: The motion of an object whose acceleration is directly proportional but opposite in direction to the object's displa...
Describing Oscillations An oscillation is defined as follows: The repetitive variation with time t of the displacement x of an object about the equilibrium position (x = 0) A pendulum oscillates ...
Investigating Gas Laws Investigating Gay-Lussac's Law Aim of the Experiment The aim of the experiment is to investigate the relationship between the pressure and the temperature of a gas at consta...
Mole Calculations The Mole The mole is one of the seven SI base units It is used to measure the amount of substance One mole is defined as follows: The amount of substance that contains as many el...
Kinetic Model of an Ideal Gas Gas Pressure A gas is made of a large number of particles Gas particles have mass and move randomly at high speeds Pressure in a gas is due to the collisions of the ga...
