Investigating atomic number 7s 2nd Law of Motion apply an oxygenise-track Introduction My experiment is investigating the Newtons 2nd natural law of gesture by using an Air-track. The melodic phrase-track can enduringness the aerial tramway frictionless by testing the velocity with different weights and shows that F=ma. question question How much acceleration does the frictionless tram has? Aim Use the air track to measure the acceleration of the no friction streetcar by hanging with different quid of weights. Apparatus * 1 air track * Weights (40g, 50g, 60g, 70g, 80g, 90g, 100g) * 1 thread (bigger than 200cm) (plastic) 1 frictionless trolley (160g) * 1 pair of scissors * 2 sensors * 2 clamps * 1 ruler * 2 lively gates * 1 Pulley * 1 data logger Variables Independent the mass pulls down the frictionless trolley. Dependent the duration taken when the frictionless trolley go through two high spirits gates. learn the distance of the light gates and the top of the inn ing of the light gates. Uncertainties The strength of the plastic draw after pulling a percentage of weights. Procedure 1. Put two light gates 50 cm in the midst of each other, the lights gates hanging by the clamps. 2.Hang the hang one side to the frictionless trolley and another side on the hook which for hanging the weights. 3. Put the string on the wheel. 4. Put the frictionless trolley on the air-track at the distance of one hundred seventy cm. 5. Hang 40 g weights on the hook. 6. The frictionless trolley move fore by the weights. The light gates leave alone automatically recording the speed of the trolley takes and record down the data on the data logger. 7. Repeat the lab 5 times and do with other weights 50g, 60g, 70g, 80g, 90g, 100g as the same procedure. Diagram Out filiation (not to scale) How the air track worksAir track is a device utilize for study motion in start friction environment. The air pump erupt of the small holes on the track and that allows the tro lley got lifted and frictionless. Data Table certainty The newtons second law is the rate of change of pulse of a embody is directly proportional to the harebrained force acting on the body and takes place in same direction. Its according to my lab that the trolley is pitiful in one direction. Also the interpret shows the a curve which shows the change of momentum is directly proportional to the unbalanced force olley. acting on the t
