1H10 - Action and Reaction

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 - Recoil

DCS #	Demonstration	Abstract/Description
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.
