Newton's Third Law
PIRA classification 1H
Third law: The mutual forces of action and reaction between two bodies are equal, opposite, and collinear.
15 Demonstrations listed of which 11 are grayed out.
Grayed out demonstrations are not available or within our archive and are under consideration to be added. |
1H10. Action and Reaction
PIRA # |
Demonstration Name |
Abstract |
1H10.10 |
Push Me, Pull Me Cart |
Two people on roller carts. Both people either pull on each end of a rope or push on each end of a long stick. |
1H10.12 |
Carts and Ropes |
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 |
Cut or Burn a string holding a compressed spring between two air gliders. |
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. See [http://scitation.aip.org/getpdf/servlet/GetPDFServlet?filetype=pdf&id=PHTEAH000010000004000208000001&idtype=cvips&doi=10.1119/1.2352167&prog=normal TPT 10(4), 208]. |
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. See [http://scitation.aip.org/getpdf/servlet/GetPDFServlet?filetype=pdf&id=PHTEAH000010000009000488000001&idtype=cvips&doi=10.1119/1.2352348&prog=normal TPT 10(9), 488]. |
1H10.25 |
Helicopter Rotor (Broken) |
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. See [http://physicslearning.colorado.edu/PIRA/Sutton/PARTI.pdf#pagemode=none&page=1 Sutton M-122]. |
1H11. Recoil
PIRA # |
Demonstration Name |
Abstract |
1H11.10 |
Floor Cart and Medicine Ball |
Stand on a roller cart and throw a heavy medicine ball or Styrofoam ball. |
1H11.11 |
Stool on a Conveyor |
Throw a ball sideways 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 (Being Made) |
A liquid nitrogen powered cannon on wheels shoots heavy and light stoppers. |
1H11.31 |
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. |
