3
Classic Parachute Example Drag and velocity relationship.[1]
4
More Examples Misalignment error in G.P.S. [2] Car crash computer modelling. [3]
5
Results of ODE Elapsed time is 1.482735 seconds.
6
Graph that shows the difference in the exact analytical solution versus Euler’s solution with and without friction.
7
Our Innovation
8
We created a game. Aim: Fire the projectile out of box and land in designated area. Method: Guess speed and angle of the projectile.
9
Problems Encountered Ball would penetrate past boundary before bouncing off. To counteract this we halved the step-size when it came close to the boundary
10
Problems Encountered Our code, when executed was not particularly efficient. If given more time we could implement the Runge-Kutta method or the Adams-Bashforth method to improve efficiency.

12
Response to Article Disagree with the article Quality and quantity Overseas expansion is seen as a positive step for businesses Second level education not to blame [4]
13
Response to Article Methods of improvement A Week Of Wonder [5] Search for problem internally rather than blaming external factors
