Simple Pendulum<br />
The accurate determination of time has been an extremely<br />
important part of physics. All events happen within a<br />
timed component. The simple pendulum is one method to<br />
determine this variable. This kit studies the pendulum and<br />
evaluates which of its factors are used in determining time.<br />
Meets national standards. For 36 students. Grades 9-12. (•1)<br />

SB48466M — $120.80<br />
Atwood Machine<br />
This simple, economical mechanism enhances the understanding<br />
of the effects of linear and angular acceleration.<br />
Machine consists of two low-friction pulleys attached<br />
to a support rod that can be mounted to a ring stand or<br />
other support. Can be used with most pulley cords, mass<br />
hangers, and masses. Elementary school through college.<br />
Sh. wt. 0.09 kgs.<br />
SB34813M — $65.40<br />
Tabletop<br />
Pulley<br />
Great for experiments<br />
calling for a<br />
pulley at different<br />
heights. Adjusts over<br />
a height range of 10<br />
cm, locks in place<br />
with a thumbscrew,<br />
and rotates a full<br />
360°. Two-piece<br />
apparatus consists<br />
of glass-filled, nylonmolded<br />
clamp and<br />
pulley with blue<br />
sheave attached to a<br />
stainless steel rod. Clamp fits tables up to 5 cm thick. Rod<br />
is 5 7 ⁄8" L x 3 ⁄8" dia. Coefficient of friction a very low .04.<br />
Tip: Use this pulley in acceleration labs. Clamp to table,<br />
tie weights to cord, slip cord over pulley, and accelerate<br />
objects with falling weights. Sh. wt. 0.20 kgs.<br />
