1H10.10 Push Me, Pull Me Carts
Concepts
Newton's third law
Overview
Two people on rolling platforms pull each other using a rope.
Details
Equipment
- [1] Skateboard
- [1] Dolly
- [1] Rope
Important Notes
- The skateboard's friction is stronger than the dolly's friction, so it's not a completely fair demo. You may want to put the more massive student on the skateboard to ensure the expected qualitative result for this experiment.
Script
- Ask for student volunteers to sit on the skateboard and dolly.
- Have them pull each other with the rope.
