These free-running plastic pulleys are durable in design.

Sturdy box for investigating frictional forces.

Instantly transform potential energy into kinetic energy.

The perfect kit for students and educators studying gravitational potential energy, translational and rotational kinetic energy.

Allow Students to Plot Trajectories

Ideal for studying collisions in two dimensions, these pucks can be supported on plastic beads or levitated with air from the balloons to reduce friction. Use on any smooth, flat surface. The pucks measure 10 cm in diameter, and one puck is twice the mass of the other two.

Nearly frictionless, accurate, durable.

This large aluminum pulley is a great alternative for Atwood’s Machine experiments.

This sturdy Hooke's Law apparatus features a mirrored scale to eliminate parallax error.
