1H10.10 |
push me pull me carts |
Two people stand on roller carts and both pull on a rope or push with a long stick. |
1H10.10 |
push me pull me carts |
Two people stand on roller carts and both pull on a rope. A long stick may be substituted to allow pushing. |
1H10.10 |
rope and carts |
People on two identical roller carts pull each other with a long rope. |
1H10.11 |
rope and carts |
All the things you can do standing and running on carts with and without ropes. |
1H10.12 |
rope and carts |
Stand on a cart holding a rope passing over a pulley to a weight slightly less than static friction, then pull the rope. |
1H10.15 |
reaction gliders |
Burn a string holding a compressed spring between two air gliders. |
1H10.20 |
Newton's sailboat |
Propel an air glider with a battery powered fan, then attach a sail directly in front of the fan. |
1H10.20 |
Newton's sailboat |
A battery powered fan and sail can be mounted on a air track cart. Three cases are demonstrated: 1) sail attached, fan not attached; 2) both sail and fan attached; 3) fan attached, no sail. |
1H10.20 |
fan car with sail |
A sail is placed in front of a battery powered fan on a cart. |
1H10.21 |
Newton's sailboat |
A balloon provides an air source on one cart, a sail is mounted on another cart. Hold each stationary in turn. |
1H10.25 |
helicopter rotor |
A symmetric propeller deflects air down, causing upward lift. |
1H10.30 |
cannon car |
A small brass cannon mounted on one car fires a bullet into a wood block on another of equal mass. A string tying the carts together will result in no motion. |
