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 today proportional to the send away force performing on it and mutually proportional to its hole (VUILLE, 86). This second law loafer 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 quickening of the object, m is the objects locoweed Fnet represents the vector spirit of all the forces acting on the object. The Atwood railcar is an apparatus that explores the root states above. The Atwood machine is named subsequently the British scientist George Atwood. He used this catch to study the motion and measure the value of the acceleration overdue to gravity, g (Greenslade, 24). This probe has two purposes to it. The first calve of the part is to ask a = F/m by retentive ness F constant This investigating involving the Atwood machine will investigate the different aspects of a = F/m. The first part of the cognitive process holds m constant succession studying the race 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 other. m = k/a and a = k/m. 2.PROCEDURE 2.1Equipment & Materials The! key hang on of equipment used in this investigating is the Atwood machine. Two types of Atwood machines exist: a single mental block system and a parallel pulley system. This investigation uses a double pulley system, which eliminates the passing weights impinging 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 blanket(a) essay, order it on our website: BestEssayCheap.com
