DCS # | Demonstration | Abstract/Description |
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. |

1H11.01 | recoil | |
1H11.10 | floor cart and medicine ball | Stand on a roller cart and throw a medicine ball or styrofoam ball. |
1H11.10 | floor cart and medicine ball | Throw a heavy medicine ball while standing on a roller cart. |
1H11.11 | stool on a conveyor | Throw a ball while on a stool mounted on a conveyor. |
1H11.20 | tennis ball cannon | A cannon on wheels shoots a tennis ball. |
1H11.30 | liquid nitrogen cannon | A liquid nitrogen powered cannon on wheels shoots heavy and light stoppers. |
1H11.30 | liquid nitrogen cannon | A cork is shot out of a liquid nitrogen cannon. |
1H11.30 | liquid nitrogen cannon | CO2 provides the pressure to blow a cork out of a cannon on wheels. |
1H11.30 | liquid air gun | Liquid air in a bent test tube shoots a cork when the escape valve is closed. |
1H11.40 | ballistic gun | Shoot a spring loaded bifilar suspended gun. Measure the muzzle velocity by range and the recoil by adjacent scale. |
1H11.41 | open cannon | A hole in the back of a rail mounted gun allows the gasses to escape or not to show the difference on recoil. |
1H11.44 | bent gun | A spring loaded gun firing a steel ball has a barrel bent 90 degrees to show recoil opposite the exit direction instead of the firing direction. |
