Push the cart and eject the steel ball from the spring-loaded barrel. The ball falls back into the barrel of the moving car, demonstrating that the forward motion of the ball is the same as the vehicle from which it was ejected. Includes activity guide.

Push the cart and eject the steel ball from the spring-loaded barrel using a remote control. The ball falls back into the barrel of the moving car. Includes activity guide.

This clamp can be attached to any standard meter stick. It is used as a knife-edge fulcrum for supporting the meter stick in the inverted position.

Rugged plastic pulley with deep V-grooves mounted on a metal clamp. The sheave is 50mm in diameter. Clamp can be mounted on surfaces up to 35mm thick.

Investigates conservation of momentum and kinetic energy change in collisions. It can also be used to compare elastic and inelastic collisions. Includes 2 steel balls, a glass ball, a hollow wooden ball, and a plumb line. Includes activity guide.

An set of 12 drilled balls for all your pendulum experiments. Set contains 2 each 25mm balls of brass, aluminum, steel, wood, cork, and copper, in a plastic box for easy storage. Feature 3mm countersunk holes so pendulum cord knots can be recessed.

A comprehensive set of 12 balls. Includes 1 each of 25mm drilled aluminum, copper, steel, and wood balls, 2 each of 25mm drilled brass balls, two each of solid steel balls, 38mm diameter brass, steel, and copper balls with hooks, and a 38mm cork ball.

Sturdy support for meter stick demonstration balances and torque experiments. The cast metal support is 18.5cm high. Requires knife-edge clamps, slotted weights and hangers, and a meter stick.

Fan Cart powered by two AA size batteries (not included) demonstrates Newton's principle of action and reaction.The propeller delivers a thrust of about 88mN, accelerating the cart at 0.4 m/s2. Includes activity guide.

Set includes a friction block and a friction board. The friction block has a hook for a spring scale and three compartments for additional weights. he set comes with three 50g weights and a 100g spring scale. Includes an activity guide.

This friction box is used for coefficient of friction studies when larger loads are required. The 6" x 3.5" x 2.5" box will accommodate a load of 2kg or more. Constructed of smooth sanded wood with two leather strips attached to the bottom.

The Kit contains a variety of custom made and unique components and accessories needed for 15 different activities. Includes a lab activities manual (over 80 pages) and a CD containing a slide presentation of all experiments that can be performed.

This economical version of our Forces & Simple Machines Kit, this set is ideal for introducing students to the concepts of changing force by levers and pulleys, and the notion of mechanical advantage. Includes a detailed activity guide.

The set features a dual scale, an outer scale for accurate pulley positioning,and an inner scale for orienting a tracing paper overlay. The set includes four complete weight sets, four pulleys with clamps and two sets of strings. Includes activity guide.

Quantitatively show the principles related to Hooke's Law with this complete apparatus. Includes activity guide.
