A Catapult Investigation Essay Example A Catapult Investigation Essay A Catapult Investigation Essay The point of this trial is to research how far a bit of square would travel utilizing a launch with various loads on the square and distinctive power applied to the catapult.FrictionI know from course readings and from exercises that grinding will influence how far certain item ventures. Since Im not going to change the contact or not going to change where I will do my test I dont need to stress over this factor.HypothesisMy speculation for this investigation is the more power you apply to the elastic band the further the wood will travel however the more weight you put on the square of wood the less separation its going to cover.Apparatus* A stool* Rubber band* Newton meter* Weights* A meter stickMethodI will do trial of 5, 10, 15 and 20 newtons power each with and without loads. I will put up to 3 loads on the square. I will complete 5 rehashes for each test. Right off the bat we needed to set up the stool then we needed to discover a spot to do the test however we ensured that we did the analysis in a similar spot all through. We recorded our outcomes on a book and put it on to a table.Fair testThe factors we didnt change so as to make this as reasonable test were the hardware and the spot we did the test. We did this by composing our name in the gear we used.DiagramSafetyWhen we were doing the trial we ensured nobody remained before the wood which would have been discharged. We wore goggles so our eyes wont get harms if the elastic band flies at us.Other PrecautionsDuring the examination we should ensure that we dont make any human mistake, for example, recording the separation wrongly or plotting the outcomes wrong.These are the results(in cm)5N5N+1Weight5N+2Weights5N+3Weights161251151062161373159531775410N10N+1Weight10N+2Weights10N+3Weights796555387762494176595842767153367863474515N15N+1Weight15N+2Weights15N+3Weights13011091601551169864121119100711201159559118114945720N20N+1Weight20N+2Weights20N+3Weights2051691321152672101341042501211351052302081301102001 91121102ObservationsStandard DeviationI did standard deviation to discover how spread the gathered information is.

My speculation was the more power you apply to the elastic band the further the wood will travel however the more weight you put on the square of wood the less separation it will cover. As Newton said When an item picks up constrain it will quicken or decelerate the speeding up or deceleration is corresponding to the resultant power. This clarifies when the square of wood was discharged at 20 Newtons the power it picked up was a lot more noteworthy than the grating; this is the reason it could go for more noteworthy separation. Be that as it may, when a similar square of wood was discharged at 5 Newtons the square of wood didnt go far enough this is on the grounds that the erosion was more prominent than the power discharged by the bit of wood.EvaluationI feel that these outcomes are bad since we didnt check the flexibility of the elastic band.Elasticity of the elastic bandI know from the Internet that versatility of a typical elastic band will change w hen you continue extending yet there is a breaking point when the elastic band won't stretch further. I put 50g load on another elastic band and estimated the amount it extended. I at that point took the weight and extended the elastic band multiple times and put 50g weight and estimated it. I did this until I got a similar outcome multiple times. These are the results:155mm179mm200mm200mm200mmThese results show that the versatility of the elastic band will change however there is a breaking point to it. On the off chance that I had done this and utilized a similar elastic band, at that point I can be certain that the outcomes are not off-base. I think I gathered enough outcomes.
