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...
Circular Motion Velocity?and?acceleration?are both?vector?quantities An object in?uniform circular motion?has a constant?linear?speed However, it is?continuously changing direction.?Since ve...
How do I use the binomial theorem for fractional and negative indices? How do we use the binomial theorem to estimate a value? The binomial expansion can be used to form an approximation for a valu...
