Discussing A Catapult

Discussion

The results did not give enough accurate data, due to the ability of the catapult and the weights used, the point at which the projectile stopped being efficient was not evident. If the experiment had been undertaken in more controlled and technology used more efficiently, like a robotic catapult, than the effect of weight on the motion of a projectile would have become more apparent. Furthermore, the reliability of the experiment would be drastically increased due to the use of more accurate and more constant technology.

Air resistance would of been a major factor affecting the parabolic shape produced by the projectile as it launched. In the calculations surrounding the projectile motion of the objects air resistance is considered
Though the catapult was taped to the ground the tape could not hold the catapult down effectively, thus, making the catapult lift of the ground when a force was exerted on it. As a result the catapult would have moved in tiny increments, allowing for inaccuracy in the reading of the projectile motion against the height board. However, the effect of these movements would have been insignificant against the imprecision of the technology and height board used. An improvement would be to be use more tape to hold down the catapult. This would mean that the catapult would not move, thus not affecting the
When examining the footage of the projectile against the height board individual experiments meant that only one set of human eyes had looked at the data, whereas if the experiment had been undertaken by a group than data would have been examined by many set of eyes. Thus, the results would have been determined by many different people rather than one, effectively meaning that the results were then more reliable, because they had to have been approved by many people. However, in terms of amount learnt by the collaborative working as a group would result in lesser knowledge overall as fewer experiments had been
