Summary Notes on mechanics
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 well as the principle of terminal velocity of an object. Also, the physics behind vehicle safety mechanisms is also explored. There is also a detailed explanation of how temperature is related to the internal energy of particles. The first law of thermodynamics is also explored. Furthermore, the ideal gas laws (Boyle's, Charles', and the pressure law) have all been explained fully as well as the ideal gas equation. Finally, the kinetic theory model for gases including its assumptions has been provided along with several equations related to this theory. The principle of conservation of momentum is stated as well as the difference between elastic and inelastic collisions. Finally, the differences between work energy and power of a body as well as their relevant equations are also given.
