This is a simple simulation of Atwood's machine problems.
The Atwood 1 page shows two hanging masses pulling the system in opposite directions. Possible uses include:
The Atwood 2 page has the friction force between the left mass and the table opposing the pull from the hanging mass. The friction can be adjusted from frictionless to a static coefficient of 1.0. The coefficient of kinetic friction is assumed to be 0.05 less than the coefficient of static friction, except for very small values. Possible uses include:
All controls except the reset button are disabled while the animation is running.
The pulley and string are assumed to be frictionless and massless.
