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...
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...
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...
What are Permutations? A permutation is the number of possible arrangements of a set of objects when the order of the arrangements matters A permutation can either be finding the number of ways to...
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 ...
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...
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...
What is meant by counting principles? The fundamental counting principle states that if there are m ways to do one thing and n ways to do another there are m × n ways to do both things Applying cou...
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...
