.The Spark Generator produces high voltage pulses at variable frequencies. The precisely timed sparks leave a permanent series of dots, like paw prints in the snow. This recording method is useful for dynamics experiments, since the record is permanent and there is no frictional drag on the moving body.

.Our set studies the simple harmonic motion of swinging and bouncing pendulums. A horizontal rod, from which the pendulums hang, clamps onto a vertical support rod with a meter scale and a cast-iron tripod base. The swinging pendulums have a 19 mm diameter brass bob and an acrylic bob of the same diameter together with a length of flexible cord for suspending them so that students can measure the effect of length and bob mass. The spring...

.Our updated Atwood's Machine demonstrates the combined effects of linear and angular accelerations. A string carrying two weight holders passes over a large, ball-bearing mounted pulley. The linear inertia and the rotational inertia of the system are equal, so both mass and moment of inertia must be considered in calculating the acceleration. Adding light weights to one of the weight holders produces acceleration. Dropping the platform and...

.After two centuries, still the most elegant determination of g. In 1817, Kater, following a suggestion from Bessel, developed a reversible pendulum that made possible an extremely accurate measurement of the acceleration due to Earth's gravity, g. The reversible pendulum is a pendulum that can be swung from either of two pivot points. When the mass distribution of the pendulum is adjusted so that the periods are the same from either pivot,...

.Calibrated in Watts/meter2, the Radiometer will measure the energy of direct sunlight or the warm spot left by a human hand pressed on a wooden desktop. The thermopile detector consists of a series of tiny thermocouples wired in series. The thermopile mounts in a substantial aluminum housing to maintain temperature stability. An integral shutter mounted in the housing cuts off the incoming radiation when adjusting the zero offset of the...
