1E10.10crossing the river1E10.10Pull a sheet of wrapping paper along the lecture bench while a toy wind up tractor crosses the paper.
1E10.10crossing the riverAJP 48(10),887A 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.
1E10.10crossing the river6-4.10A wind up toy is placed on a sheet of cardboard that is pulled along the table.
1E10.10crossing the riverM-75A small mechanical toy moves across a rug which is pulled down the lecture table.
1E10.10bull dozer on moving sheet (2D)Disc 02-08The bulldozer moves across a sheet moving at half the speed of the bulldozer or at the same speed.
1E10.11toy tractor driveAJP 35(2),xixOn using toy tractors in kinematics demonstrations.
1E10.15moving blackboardTPT 19(1),44Using a large movable reference frame on wheels and a walking student, equations of relative speed can be deduced by non science majors.

1E10.20Frames of Reference film1E10.20The classic film available on video disc permits use of selective parts.
1E10.22photographing relative velocity6-4.1Toy bulldozers, blinkies, and a camera give a photographic record of relative velocities.
1E10.23Galilean relativity7-3.1A Polaroid camera and blinky, each on a cart pushed by a toy caterpillar, show the various cases of relative motion.
1E10.31stick on the caterpillerMb-30A small stick placed on the top tread of a toy caterpillar moves twice as fast as the toy.
1E10.41inertial reference framesAJP 34(1),xviiiTwo X-Y axes, one on a moving cart, and "cord" vectors are painted with fluorescent paint and viewed in black light.
1E10.41inertial reference frames7-3.2Complicated. Look it up.
