Topple or slide?
Push a tall block with a growing force. It either slides first or tips over its front edge first.
What to notice
Pushing higher or using a narrower block makes tipping happen before sliding.
Key relation
Slides at F = μmg ; tips at F = mg (b/2) / h_F
Try this
Push at the top of a tall, narrow block on a high-friction floor.
What you can change
- Block width: 0.2 to 1 m
- Block height: 0.4 to 2 m
- Push height (fraction of H): 0.1 to 1
- Floor friction μ: 0.1 to 1
