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.

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.
When two objects of unequal mass are hung vertically over a frictionless pulley of negligible mass as in Figure 5.14a, the arrangement is called an Atwood machine. The device is sometimes used in the laboratory to determine the value of g.
Atwood's Machine Frictionless case, neglecting pulley mass. Application of Newton's second law to masses suspended over a pulley: Atwood's machine
The purpose of this activity is to study the relationship between net force, mass, and acceleration as stated by Newton’s 2nd Law, using an Atwood’s Machine apparatus, built with a PASCO Super Pulley. The Super Pulley has very low friction and small mass.
Atwood's Machine The Atwood's Machine Interactive provides an environment that allows the learner to explore two-mass systems. 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.
