CATAPULT TESTING

Last week room 15 tested the modifications they had made to their model catapults.

First we decided upon the main variables of a catapult that effect the distance a projectile travels. These variables are lever length, mass of projectile and the angle of the lever arm.

Each group chose one variable to modify on their catapults and then tested the modifications to see whether it made a difference to the distance their projectile fired. The results of the testing were mapped on a graph.
