Make the idea your own
- 1Start with the push below the threshold: the block stays at rest.
- 2Increase the push until the forces stop balancing.
- 3Run the demonstration and compare the force arrows.

The relationshipNet force = push − opposing friction
Explain the experiment
When the goal is met: The push exceeds friction by 4 N, so a stationary block accelerates forwards in this model.
