A recap of level 2 physics concepts.
Impulse & Conservation of Momentum pg89
In level 2 physics the concept of conservation of momentum was introduced: The total momentum of a system is conserved, unless acted on by an external force.
Last year you only looked at conservation of momentum in one dimension, this year we consider two dimensions. The same law applies: The total momentum of a system is conserved, unless acted on by an external force. Because momentum is a vector this means the total vertical momentum is conserved and the total horizontal momentum is conserved.

Centre of Mass pg 102
The center of mass is the point at which all the mass can be considered to be "concentrated".
A force acting towards (or away from) the centre of mass will cause linear motion but no rotation.
You can use the following equation for calculating the position of the centre of mass of a system (it is easier to use one of the masses as x=0 position):

This website from the University of Salford in Manchester has some interesting (slightly crusty) animation/simulations that help explain many of the concepts of SHM. Including this page on damping.
