MMW-PMCH-0104

This is to demonstrate the principle of conservation of momentum and showing that

momentum is a vector quantity having both magnitude and direction.

The

apparatus comprises: A curved runway 275 mm long and 65 mm high at
its highest point, having a groove 8 mm wide down which a steel ball is
rolled. An

index mark at the top of the runway is provided so that the
ball may be rolled from a constant height ensuring reproducibility of
results. A metal

plate 100 mm square is attached to its lower end which
enables the apparatus to be fixed to the edge of a bench by a G-clamp.
The plate also has a slot

for the attachment of object sphere support.
An object sphere support is an adjustable device which attaches to the
mounting plate of the runway and

will support a ball either exactly
opposite the end of the runway for head on collision or slightly offset
for oblique impact. Supplied with a plumb

bob for making the plumb line
and Two spheres (steel ball bearings 16 mm diameters).
