"Projectile"

Watch work and energy intercept.

Hands-On and Versatile Demonstration of Mechanics

Demonstrate Newton’s First Law

The Quantitative Centripetal Force Apparatus' simple concept and robust construction guarantee reliable lab success.

Add Some Momentum To Your Physics Lessons

This is an excellent, inexpensive apparatus for experiments in precession, inertial guidance, and gyroscopic stabilization.

Clear, Concise Demo of Conservation of Energy

Present a Wide Variety of Standard Force and Motion Activities.

This launcher is easy to assemble, and it delivers consistent classroom results.

Versatile Unit Tests Several Factors of Friction

The activity includes one triple sheave, one double sheave, and two single sheave pulleys, as well as a beautifully illustrated activity guide with questions, making it ideal for single student study or as a demonstration unit.

This apparatus verifies that that the amount by which a material body is deformed (the strain) is linearly related to the force causing the deformation (the stress).

Easily Explain Rotational Inertia

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

This unique metal launcher has multiple settings, so launch speed and angles may vary.

Compare the falling rate of a feather and a guinea (coin) with air resistance and in a vacuum.
