Extended Essay Reports and Exemplars
Please read the reports before reading the essays. The reports contain valuable information directly from IB examiners on what was successful and what was not. Also remember that just because something was successful in an exemplar, it does not mean that this is how the essay must be written. There are many different ways to get a good mark on your extended essay and it is important that you find the approach that best suits the paper you are writing. The exemplars below are only meant to clue you in on the type of analysis examiners like rather than providing a stylistic from that you must follow.

Not sure if me telling you this is 'cheating' or not but here's an explanation:
+ Show Spoiler +
According to the momentum equation p=mv, you can get more momentum (better for pushing other things in a collision) by increasing mass or velocity. If you double mass, you double momentum. If you double velocity, you double momentum. Mass and velocity contribute equally towards the momentum.
Kinetic energy however does not work this way. The formula is KE = 1/2 m v^2. If you double the mass you double the KE, but if you double v you quadruple the KE. Therefore increasing velocity has a greater affect on KE than increasing mass would.
However, a collision between two football players is probably inelastic meaning momentum is conserved during the collision but energy is not....
There's some food for thought?
