[The note has been updated for syllabus]. All the questions in the past exam papers were analysed and there were a large amount of repetitive questions; the most noticeable ones being the definitions. The other parts of the notes were a collection of questions and answers from the mark scheme t...

Is there anything I can do to improve the notes? I'll try my best to add them!

I am sorry to see that you didn't like my notes, can you perhaps tell me what you think could be improved so that I can edit it over the summer holiday for the future students who take the exams. Thanks!

,Key Points and Definitions
[AN] Author’s Notes

** Key Points that are not “definitions” eg. ‘define...’ ‘what is meant by…’
(**The topic numbers below are according to the 2019-2021 Syllabus and the definition and key
points are all from the mark scheme up to June 2018)
https://www.cambridgeinternational.org/Images/329533-2019-2021-syllabus.pdf


1 Physical quantities and units
Scalar Quantity: has magnitude only

Vector Quantity: has magnitude and direction


2 Measurement techniques
Systematic errors: constant error (in all readings) // cannot be eliminated by averaging

// error in measuring instrument
Random errors: readings scattered (equally) about the true value // error due to

observer // can be eliminated by averaging

Precision: smallest scale division of instrument
Accuracy: how close are the readings to the true value


3 Kinematics
Velocity: rate of change in displacement
**Velocity is the gradient of the displacement time graph

Acceleration: rate of change in velocity

**Acceleration is the gradient of the velocity time graph

Difference between distance and displacement: distance is scalar, and displacement is
vector. Displacement is the shortest distance between two points, distance is the sum of

the lengths moved.

**Displacement is the area under graph of velocity time graph
[AN] You should also know the all the SUVAT equations for this part (Remember all of them,
don’t waste time to derive them).

, 4 Dynamics
Newton’s first law: a body remains at rest or at constant velocity unless acted on by a

resultant external force
Newton’s second law: Force =rate of change in momentum (Also the definition of force)
𝑚𝑣−𝑚𝑢 𝑣−𝑢
**𝐹 = = 𝑚( ) = 𝑚𝑎 !! (F = ma)
𝑡 𝑡

Newton’s third law: for every action, there is an equal and opposite reaction

Weight: weight is the force due to the gravitational field // force due to gravity or
gravitational force

**𝑊 = 𝑚𝑔

Principle of conservation of momentum: Total momentum before the collision is equal

to the total momentum after the collision when there is no resultant external force acting
/ in an isolated system

**Although momentum is always conserved, Kinetic energy my change to other form
of energy, hence energy lost from the system

Elastic collision: Total kinetic energy before collision is equal to the total kinetic energy
after the collision // relative speed of approach = relative speed of separation


5 Forces, density and pressure
Centre of gravity: the point where all the weight of the body is considered to act
Center of mass: the point on an object where all its mass is considered to act
Principle of moments: the sum of the clockwise moments about a point is equal to the

sum of anticlockwise moments about the same point
Moment of a force: product of force and the perpendicular distance from a pivot

Torque of a couple: one of the forces times by the perpendicular distance between the

forces.

Equilibrium: no resultant force and moment (torque)
Density: mass / volume

Mass: Quantity of matter in a body // property in a body resisting changes in motion

Pressure: Force per unit area (normal to the force)
