Isaac Physics, is a self assessment tool that we should use in these classes, maybe for homework's, but definitely for self preparation for exams and

Snow is falling cos of gravity,

It’s why the earth moves around the sun

Force of attraction between two point masses

Christmas physics for everyone

Force is mass times acceleration, second law of Isaac Newton,

all important when I’m on my sleigh ride

laws of physics at Christmas time

We’re gonna build a circuit tonight

having bulbs in series means if 1 bulb blows must replace it or my Christmas tree won’t light.

Cooking my turkey, in an oven

making blackbody radiation

was the source of the ultraviolet catastrophe

gave us the physics we call quantum

Santa travels the world in one night,

Physics laws are broken cause Einstein says nothing can move faster than the speed of light.

Flying reindeers, complex physics

Further research must be done

Laws of physics don’t apply to Santa

No more physics for everyone.

It is important to realize that in physics today, we have no knowledge what energy is.

1. Use of calculators

Students will be expected to have an electronic calculator conforming to the examination regulations for the duration of the course and when answering the examination paper. It is recommended that students have available the following keys:

In carrying out calculations, students should be advised to show clearly all expressions to be evaluated using a calculator.

The number of significant figures given in the answer to a numerical problem should match the number of significant figures given in the question.

2. Mathematical requirements

The physics syllabus does not require Higher level mathematics. Higher level physics may include some of the optional work of Ordinary level mathematics.

There is no requirement for the use of calculus techniques.


Students should be able to

• understand the concept of significant figures

• recognise and use significant figures as appropriate

• recognise and use expressions in decimal and

standard form (scientific) notation

• recognise and use prefixes indicating multiplication by 10-12, 10-9, 10-6, 10-3, 103, 106, 109

• use an electronic calculator for addition, subtraction, multiplication and division and for finding arithmetic means, reciprocals, squares, square roots, sines, cosines and tangents, exponentials, logarithms, and their inverses

• make approximate evaluations of numerical expressions and use such approximations to check

calculator calculations.


Students should be able to

• change the subject of an equation

• solve simple algebraic equations

• substitute for physical quantities in physical equations using consistent units

• formulate simple algebraic equations as mathematical models of physical situations

• comprehend and use the symbols >, <, ∝, =, x, Δx.

Geometry and Trigonometry

Students should be able to

• calculate the area of right-angled triangles, circumference and area of circles, surface area and

volume of rectangular blocks, cylinders and spheres

• use Pythagoras’ theorem, similarity of triangles, the angle sum of a triangle

• use sines, cosines and tangents in physical problems

• recall that sin θ ≈ tan θ ≈ θ/radians, and cos θ ≈ 1 for small θ

• translate between degrees and radians and ensure that the appropriate system is used.
