Atwood Machine
Definition
An Atwood machine is a simple mechanical device consisting of two masses connected by an inextensible string that passes over a pulley. It is used to study the effects of gravitational forces on objects in equilibrium.
Analogy
Think of an Atwood machine as a tug-of-war between two people of different weights. The heavier person will experience more downward force, causing them to pull harder, while the lighter person will experience less downward force and pull less.
Related terms
Tension: The pulling force transmitted through a string, rope, cable, or any other type of flexible connector.
Equilibrium: A state in which all forces acting on an object cancel out, resulting in no net acceleration.
Pulley System: A system consisting of one or more pulleys used to change the direction or magnitude of applied forces.
