Atwood's machine is a device invented in 1784 by the English physicist Rev. George Atwood. (See Fig. \(\PageIndex{1}\) ) The purpose of the device is to permit an accurate measurement the acceleration due to gravity \(g\).
The Atwood Machine is a pulley system consisting of two weights connected by string. We will assume no friction and that both the string and pulley are massless. If the masses of the two weights are different, the weights will accelerate uniformly by a.
27 Μαΐ 2024 · Devised in 1784 by the English scientist George Atwood as a laboratory experiment, this apparatus is designed to explore the laws of uniformly accelerated motion and the effects of gravity. Design and Working Principle. The design of Atwood’s Machine is elegantly simple.
The acceleration is. a = m/s². and the tension is. T = N. Change any of the mass or weight values and the resulting acceleration and tension values will be calculated. Index. Newton's laws. Standard mechanics problems. HyperPhysics ***** Mechanics.
The Basic Approach to Solving a Two-Body Problem. The solution to any two-body problem (including Atwood's Machine problems) will typically include two analyses: A System Analysis: Used to determine the acceleration. An Individual Object Analysis: Used to determine an “internal force” Straightening the System. Example 1.

An Atwood's machine (two masses connected by a string that stretches over a pulley) and a modified version of the Atwood's machine (one of the masses is on a horizontal surface) can be explored.
