1E10.10 |
crossing the river |
Pull a sheet of wrapping paper along the lecture bench while a toy wind up tractor crosses the paper. |
1E10.10 |
crossing the river |
A long sheet of paper (river) is pulled along the table by winding on a motorized shaft. A motorized boat is set to cross the river. Marking pens trace the paths. |
1E10.10 |
crossing the river |
A wind up toy is placed on a sheet of cardboard that is pulled along the table. |
1E10.10 |
crossing the river |
A small mechanical toy moves across a rug which is pulled down the lecture table. |
1E10.10 |
bull dozer on moving sheet (2D) |
The bulldozer moves across a sheet moving at half the speed of the bulldozer or at the same speed. |
1E10.11 |
toy tractor drive |
On using toy tractors in kinematics demonstrations. |
1E10.15 |
moving blackboard |
Using a large movable reference frame on wheels and a walking student, equations of relative speed can be deduced by non science majors. |
1E10.20 |
Frames of Reference film |
The classic film available on video disc permits use of selective parts. |
1E10.22 |
photographing relative velocity |
Toy bulldozers, blinkies, and a camera give a photographic record of relative velocities. |
1E10.23 |
Galilean relativity |
A Polaroid camera and blinky, each on a cart pushed by a toy caterpillar, show the various cases of relative motion. |
1E10.31 |
stick on the caterpillar |
A small stick placed on the top tread of a toy caterpillar moves twice as fast as the toy. |
1E10.41 |
inertial reference frames |
Two X-Y axes, one on a moving cart, and "cord" vectors are painted with fluorescent paint and viewed in black light. |
1E10.41 |
inertial reference frames |
Complicated. Look it up. |
