Newton's Second Law: The Atwood Machine

1.INTRODUCTION Sir Isaac Newton produced three natural laws of bowel movement. Newtons second law of motion states that, the speedup (a) of an object is straight off proportional to the send away force performing on it and mutually proportional to its hole (VUILLE, 86). This second law foot be written into mathematical terms and written as: a = Fnet /m However, the equality in a high place is more commonly seen as: Fnet = ma In these equations a represents the acceleration of the object, m is the objects cumulus Fnet represents the vector plaza of all the forces acting on the object. The Atwood motorcar is an apparatus that explores the thought states above. The Atwood machine is named subsequently the British scientist George Atwood. He used this tress to study the motion and measure the value of the acceleration repayable to gravity, g (Greenslade, 24). This probe has two purposes to it. The first region of the part is to analyze a = F /m by retentivity F constant This investigating involving the Atwood machine will investigate the different aspects of a = F/m. The first part of the social occasion holds m constant succession studying the kinship of F to a by fastener the F of the arranging. Looking at the equation a = F/m, acceleration and force should be directly proportional to adept another. F=ka and a=F/k.

The second part of the procedure holds F constant and investigates the relationship of a to m by altering the total mass of the system. Again, based on the equation a = F/m, acceleration and mass should be inversely related to each ot her. m = k/a and a = k/m. 2.PROCEDURE ! 2.1Equipment & Materials The key foregather of equipment used in this investigating is the Atwood machine. Two types of Atwood machines exist: a single closure system and a parallel pulley system. This investigation uses a double pulley system, which eliminates the passing weights hitting each other. Figure 1 depicts the setup of the Atwood machine. The base of the Atwood machine consists of support rods connected...If you want to draw in a liberal essay, order it on our website: OrderCustomPaper.com
