v=u+at
v^2=u^2+2as
s=ut + \frac{1}{2}at^2
s=\frac{1}{2}(u+v)t
Summary/Background
In the exam, start by writing down these important formulae:
v=u+at
s=ut+\frac{1}{2}at^2
s=vt-\frac{1}{2}at^2
v^2=u^2+2as
s=\frac{1}{2}(u+v)t
Kinematics is a branch of mechanics which describes the motion of objects without the consideration of the masses or forces that bring about the motion. In contrast, dynamics is concerned with the forces and interactions that produce or affect the motion.
Kinematics studies how the position of an object changes with time. Position is measured with respect to a set of coordinates. Velocity is the rate of change of position. Acceleration is the rate of change of velocity. Velocity and Acceleration are the two principal quantities which describe how position changes.

Glossary
acceleration
the rate of change of velocity with time. It is a vector quantity with magnitude and direction.
dynamics
The study of the motion of an object or system of objects.
kinematics
The study of the motion of an object or system of objects, without reference to the actions of masses or forces.
rate of change
the derivative; a measurement of how a function changes when its input changes.
suvat
an acronym used in Mechanics for the constant acceleration formulae, where s is displacement, u is initial velocity, v is final velocity, a is acceleration and t is time.
union
The union of two sets A and B is the set containing all the elements of A and B.
velocity
the rate of change of displacement. It is a vector quantity with magnitude and direction.
