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.
