How to interact
Drag pullers onto their team’s rope. Keyboard: Enter/End to attach, Home to return, arrows to change knots.
Force set · press Go to observe
- Left team
- 0 N
- Right team
- 0 N
- Net force
- 0 N
- Velocity
- 0.0 m/s
The teams are balanced. Add 50 N to one side and observe the net force and cart.
Model notes
- The model is one-dimensional and neglects air resistance; g = 9.8 m/s². Skateboard friction is taken as zero.
- Kinetic friction is 0.75 times maximum static friction. Friction is rounded to N as in the source. Velocity becomes zero if friction would reverse it in one time step.
- Up to three objects can be stacked. The mystery mass is hidden but still affects acceleration.
- The 40 m/s speed limit and tug-of-war timing support observation; they are not physical speed limits. The bucket smooths seven acceleration samples.
