Examples Models
The following examples will hopefully give ideas for the best way to lay out models. While there is
no right or wrong way, always prioritise readability.
Example 1: Dynamic Systems
The above shows the general approach to modelling dynamic systems. You calculate the force, use
Newton’s 2
nd
law to calculate the acceleration, integrate to get the velocity
and then integrate
again to obtain the position.
The above model is a general guide, it can get a bit more complicated. For example, the mass is
required to calculate gravitational forces. It is also possible that the mass will be a function. For
example, a rocket losses most of its mass as the fuel is burnt off.
