Customer Comments

"Michael has tutored my twin daughters throughout this year & has helped them tremendously with their GCSE Exam/Assessments, during the pandemic. He has been a great tutor to both of them, patient, thorough & always well prepped with the maths subjects that they needed to cover. We really appreciate all the help that he has given them & would highly recommend him as a tutor."

"MS has been a great success in both re-engaging & encouraging my son's confidence in mathematics. He quickly saw where the weaknesses were, which were addressed & supported with great patience, & carefully developed my son's learning capabilities. Very much appreciated!"

Physics Equations & Data

Equations are central to understanding physics. Each examination boards issues a list of equations for use in their tests which are either to be memorised or given to the candidate in a booklet.

Rules for Divisibility

Divisible By" means "when you divide one number by another the result is a whole number. Numbers like 555 are clearly divisible by five, but could you see that 555 is also divisible by three, fifteen, 37, 111, & 185? Methods are given here to identify divisibility by integers 2 to 12 & more should you wish.

The Equations of Constant Acceleration

Let s be the displacement, u be the initial velocity, v be the final velocity, a be the constant acceleration, & t be the time taken, then …

v=u+at
s=vt- 1 2 a t2
s=ut+ 1 2 a t2
s= u+v 2 t
v2 = u2 +2as

Further details can be found at Wikipedia: Equations of motion - Uniform acceleration

Quadratic Sequences

A quadratic sequence has n2 & no higher powers of n in its nth term (Un). The general form of a quadratic sequence is given by Un=an2+bn+c where a, b & c are numbers that can be thought of as characterising the quadratic sequence & often are to be found.

An example of a quadratic sequence is 1, 4, 9, 16, 25, ... which happens to be the square numbers. Another is 3, 6, 13, 24, 39, ... which is less easily identified as a particular sequence. To determine if a given sequence is indeed a quadratic sequence the second difference needs to be shown to be constant.

All measurements we make have a level of uncertainty

the Limitation of Physical Measurements

But how do we combine uncertainties?

● Adding / subtracting - ADD ABSOLUTE UNCERTAINTIES
e.g. A ruler with an uncertainty of 0.5mm shows a spring extends from 50.0mm to 63.5mm, so the extension is 63.5-50.5=13.5 with an uncertainty of 0.5+0.5=1. The calculated extension is (13.5±1)mm

● Multiplying / dividing - ADD RELATIVE UNCERTAINTIES
e.g. a force of (45±5)N is applied to a mass of (9±3)kg, what is the acceleration? Using Newton's 2nd Law, the acceleration is given by a=Fm, so a=459=5ms-2 with an certainty given by 545+39=49. The calculated acceleration is 5ms-2±49 or (5±2)ms-2

Moments

In physics, a moment is an expression involving the product of a distance & physical quantity, & in this way it accounts for how the physical quantity is located or arranged.
Moments are usually defined with respect to a fixed reference point; they deal with physical quantities located at some distance relative to that reference point. For example, the moment of force, often called torque, is the product of a force on an object & the distance from the reference point to the object. In principle, any physical quantity can be multiplied by a distance to produce a moment. Commonly used quantities include forces, masses, & electric charge distributions.

Photoelectric Effect

The Photoelectric effect provides evidence that electromagnetic waves have particle-like behaviour. In the photoelectric effect, electrons are emitted from a metal’s surface when it absorbs electromagnetic radiation.

Fraction, Decimals & Percents

You're unlikely to be asked to convert between one seventh & the decimal equivalent of 0.1428571428571 ...
These are, however, the same number, but in different presentations.

Evolution of Large Mass Stars

The evolution of stars with a mass higher than about 1.4MSun is different from that of smaller mass stars. Stars between 1.4MSun & 3MSun also evolve into red giants, but they end their life as supernovae, leaving behind a neutron star. Stars with a main-sequence mass of more than 3MSun evolve into red supergiants, & when these explode as supernovae they leave behind a black hole.

Internal Resistance emf & Potential Difference

In any circuit there are components that put energy into the circuit, they provide an electo-motive force (emf), & components that take energy out, they have a potential difference (pd) across them. Both emf & pd are measure in volts (V).

Types of Homework

There are seven types of homework. These are practice, preparation, extension, integration, research, application, & flipped homework.
Each type of homework has its own role for students learning. The important task for teachers is to select homework that will best provide holistic support to a student.

Abu Rayhan al-Biruni a polymath
from the Islamic Golden Age

Al-Biruni was well versed in physics, mathematics, astronomy, & natural sciences, & also distinguished himself as a historian, chronologist & linguist. He studied almost all the sciences of his day & was rewarded abundantly for his tireless research in many fields of knowledge. Royalty & other powerful elements in society funded Al-Biruni's research & sought him out with specific projects in mind. Influential in his own right, Al-Biruni was himself influenced by the scholars of other nations, such as the Greeks, from whom he took inspiration when he turned to the study of philosophy. A gifted linguist, he was conversant in Khwarezmian, Persian, Arabic, Sanskrit, & also knew Greek, Hebrew & Syriac. He spent much of his life in Ghazni, then capital of the Ghaznavids, in modern-day central-eastern Afghanistan. In 1017 he travelled to the Indian subcontinent & wrote a treatise on Indian culture entitled Tārīkh al-Hind (History of India), after exploring the Hindu faith practiced in India. He was, for his time, an admirably impartial writer on the customs & creeds of various nations, his scholarly objectivity earning him the title al-Ustadh ("The Master") in recognition of his remarkable description of early 11th-century India.

Discovery of the Nucleus

“When we have found how the nucleus of atoms is built up we shall have found the greatest secret of all — except life. We shall have found the basis of everything — of the earth we walk on, of the air we breathe, of the sunshine, of our physical body itself, of everything in the world, however great or however small – except life.” – Ernest Rutherford
