AQA A Level Physics复习笔记6.2.5 Period of Simple Pendulum
Period of Simple Pendulum A simple pendulum is another type of simple harmonic oscillator The pendulum consists of a string and a bob (a weight, generally spherical) at the end The ti...
AQA A Level Physics复习笔记6.2.4 Period of Mass-Spring System
Period of Mass-Spring System A mass and spring system is a type of simple harmonic oscillator The time period of a mass-spring system is given by: Where: T = time period (s) m = mass (kg) k ...
AQA A Level Physics复习笔记6.2.3 Calculating Maximum Speed & Acceleration
Maximum Speed The speed v of an oscillator will vary in SHM. It is: Maximum at the equilibrium position (x = 0) Zero at the amplitude (x = A) The maximum speed, vmax, is given by the equatio...
AQA A Level Physics复习笔记6.2.2 SHM Graphs
SHM Graphs The displacement, velocity and acceleration of an object in simple harmonic motion can be represented by graphs against time All undamped SHM graphs are represented by periodic fu...
AQA A Level Physics复习笔记6.2.1 Conditions for Simple Harmonic Motion
Conditions for Simple Harmonic Motion Simple harmonic motion (SHM) is a specific type of oscillation An oscillation is said to be SHM when: The acceleration is proportional to the displaceme...
AQA A Level Physics复习笔记6.1.5 Centripetal Force
Calculating Centripetal Force An object moving in a circle is not in equilibrium, it has a resultant force acting upon it This is known as the centripetal force and is what keeps the object ...
AQA A Level Physics复习笔记6.1.4 Centripetal Acceleration
Calculating Centripetal Acceleration Centripetal acceleration is defined as: The acceleration of an object towards the centre of a circle when an object is in motion (rotating) around a circ...
AQA A Level Physics复习笔记6.1.3 Angular Speed
Angular Speed Any object travelling in a uniform circular motion at the same speed travels with a constantly changing velocity This is because it is constantly changing direction, and is the...
AQA A Level Physics复习笔记6.1.2 Radians
Radians In circular motion, it is more convenient to measure angular displacement in units of radians rather than units of degrees The angular displacement (θ) of a body in circular motion i...
