Physics - Mechanics: The Pulley (1 of 2)
Michel van Biezen・2 minutes read
The Atwood machine has 8kg and 5kg masses with a frictionless system, resulting in an acceleration of 2 meters per second squared. The tension in the strings is equal on both sides of the system due to the weights and forces involved.
Insights
- The Atwood machine problem involves analyzing forces on masses in a pulley system to determine acceleration, with the key concept being the net force acting on the system.
- By applying Newton's second law (F = MA) to the forces involved, the acceleration of the system can be calculated, leading to a crucial understanding that the tension in the strings is equal on both sides due to balancing forces.
