I predict that as the force additions EssayNewtons second Law of motion ability = Mass x speedup (N) (kg) m/s (vari sufficient) (measurement) In simple terms, this means that if the force is to increase thus the acceleration must(prenominal) also increase because the mass multiplied by the acceleration must equal the force. The equation, like many others mickle be re-arranged in order to show a assertable prediction for the value in m/s that the acceleration will be the subject of the equation. Acceleration = Force (Mass / 0. four hundredkg) Mass Weight is a force. Weight is quite oftenly confused with mass, however each atomic number 53 differs to the other. Mass is measured in kilograms (kg).The pitch of an object only concerns the amount of matter an object is make up of. In contrast to the mass of an object, the weight of an object regards how much it is being pulled down to the sum total of the earth through gravity. Weight is a force and is measured in Newtons ( N). Diagram of apparatus The experiment that was carried away occurs when a slider is pulled through two go down provides via a weighted auction block upon a soft bed of air to minimalise friction powered by a vacuum attached to the air track. When the rider breaks the beam produced from Light gate 1, a recording is began by a information processing system linked up to both light gates.Once the rider cuts through the second light gate, then the timer on the computer steps automatically as the light gates poop communicate a signal to the computer. A computer is used rather than the naked eye because the computer suffer be precise to 2 decimal places (d. p). Once the slide has passed through both light gates, it is go around both light gates and the experiment is repeated. The variable for this investigation is force, that is controlled through the weights used n the pulley. The weights argon changed at five separate times, at each time a different weight is used.My variabl es be as follows 0.02 N , 0. 03 N , 0. 07 N , 0. 08 N , 0. 12 N ( N = Newtons) The set I chose are all the smallest possible values that I am able to create. In recounting to safety, there are no specific safety issues that come to into play during this particular investigation, however behaviour around the apparatus and the laboratory is always considered a safety issue. The factors that are necessary to maintain as constants throughout the experiment in order to keep a high degree of accuracy are Straight light gates (equidistant 40cm apart) Same starting point of the rider ( 5cm before the initial light gate).Mass of the rider (0. 400kg) The light gates are required to be equidistant (40cm apart) and take in order to keep the test so immaculate readings can be preserve. The mass of the rider must also be mentained at exactly 0. 400 kg because a slight chance in the weight will cause a change in the acceleration of the rider can vector sum in widespread and inconsistent r esults. It is also important to mention the starting point of the rider that must remain constant in order for the rider to pass through each light gate at the same speed during each repeat reading recorded.In addition to these points of accuracy, there are others, which prolong sufficient relevance to the experiment. The level at which the air track is must be unbroken horizontal so that the rider has neither too longer, or too shorter acceleration value that is recorded due to the slider being against or along the gradient of the air track. This can be barely modified by adjusting the track then leaving the rider without a weight and switch on the air track, if the rider remains stationary then the air track is horizontal.The experiment will be measured on 3 occasions for each variable, these repeat readings will be averaged out into a single figure to gain an accurate set of results. To prepare for the investigation, a preliminary test was carried out in order to discover whic h mass of the rider produced the most accurate results. To do this, the lightest mass of the rider was used with the lightest and heaviest weights (0. 020N lightest) and (0. 170N heaviest). The masses of the rider were the largest possible (0. 400 kg) and the smallest possible ( 0. 200kg).The results showed me that the lighter the mass of the rider, the wider the range of results that I recorded. In contrast, the heavier the mass of the rider was, the more reliable my results were because they provided the smallest range. This meant that I chose the heaviest possible weight of the rider possible, which was 0. 400kg. cleverness area O (Obtaining The Results) FORCE (N) MASS (KG) Acceleration ( m / s ) establish 1 Test 2 Test 3 Average 0. 02 0. 400 0. 05 0. 04 0. 05 0. 05 0. 03 0. 400 0. 07 0. 08 0. 07 0. 07 0. 07 0. 400 0. 18 0. 18 0. 17 0. 18 0. 08 0. 400 0. 19 0. 19 0. 21 0. 20 0. 12 0. 400 0. 31 0. 31 0. 310. 31 Skill area E Evaluation My results throughout my investigation, we re in truth accurate.The spread of my repeat readings were very small, each reading for each strength of force were close together shown a high level of accuracy throughout the investigation. All my average points that I recorded are close to the best-fit line that I have drawn, which suggests that all my results have been accurately recorded and displayed in my analysis and obtaining render sections. The procedures to which I utilise my investigation were suitable because I was able to produce an accurate set of results with relative ease.In my opinion, my evidence can support a sufficient conclusion that as that the force upon on object is like a shot proportional to its acceleration produced. My results were tested over a reasonable range and are considered accurate as they fit in with my initial theory and also they fit in with my initial predictions that I was able to produce. I was able to produce these predictions by re-arranging Newtons second law to show me what the acce leration of an object can b equal to in terms of its force and mass. (Old equation) Force = Mass x Acceleration (N) (kg) m/s (variable) (measurement) (New, Re-arranged equation)Acceleration = Force (mass / 0. 400kg) Mass I have a range of values for my force, I inputted each one of these values to gain predicted results. (When force = 0. 02) 0. 02 = 0. 05 (Actual average = 0. 05) 0. 400 (When force = 0. 03) 0. 03 = 0. 075 (Actual average = 0. 07) 0. 400 (When force = 0. 07) 0. 07 = 0. 175 (Actual average = 0. 08) 0. 400 (When force = 0. 08) 0. 08 = 0. 20 (Actual average = 0. 20) 0. 400 (When force = 0. 12) 0. 12 = 0. 30 (Actual average = 0. 31) 0. 400 As the above figures display clearly, my results are all highly accurate and sufficiently support my prediction and theory.All that remains is to discuss how I can extend my investigation. The plain point that springs to mind is to gather further results to obtain an exceptionally high level of accuracy. However, I can also look to change my variable from the force to the mass of the rider. I can do this by investigating the relationship between the mass and force on a rider to give me excess information. I can carry out these tests in the same manner as I have discussed for this particular investigation, but changing the variables used. I will use a range of variables that will support me complete my investigation reaching sufficient conclusions.
