Roll various pairs of objects
simultaneously down the inclined plane to show which ones
reach the bottom first.
Roll different solid spheres to
show that velocity is independent of mass and radius.
Show that velocity depends on mass
distribution by rolling two non-uniform cylinders of the same
mass and radius down the incline. One cylinder has a
lead core and wooden shell, the other has a wooden core and
lead shell.
Race the hoop, cylinder, and
sphere of the same radius.
Other objects to race include the water-filled (or
chicken-broth-filled) cylinder, fluid-filled sphere,
"frictionless" air puck, and the asymmetric disk.
NOTES
Prop the board on the box and
clamp the end stop over the hinged piece of metal and to the
cart.
The ruler can be used to hold the
objects in place on the ramp; this helps in releasing them at
the same time with no initial velocity.
