Atwood’s machine consists of two weights connected by a string that passes over a pulley. The demonstration shows how the machine can be used to study the laws of motion and gravity, different weights lead to different results.. It’s a practical and visual way to understand Newton’s second law of motion and the concept of gravitational acceleration.
This demonstration illustrates how a balance of forces can be achieved using a pulley system.
This demonstration illustrates how the centre of mass of an irregular shape can be found.
This demonstration illustrates the inertia of rest of the mass, which changes depending whether the mass is jerked quickly or pulled slowly.
This demonstration shows Hooke’s law, in this case for the extension of a spring. Knowing that the force applied to the spring is directly proportional to the extension caused by that force, we can find a value for the constant of proportionality that relates these quantities.
