Force & Motion Travels on a cushion of air for nearly frictionless motion! Get consistent launch results with our Air Puck Launcher! “Feet-On” Science — Air Puck Physics Kit Demonstrate Newton’s Laws, energy, and momentum with the amazing new rechargeable Air Puck! It’s perfectly balanced and glides on a cushion of air for nearly frictionless motion across any smooth surface (even low carpet!). Sturdy bumpers will survive collisions with walls, shoes, or other Air Pucks. Runs for 20 minutes after a 90-minute charge. Includes instructions and lab ideas. Our exclusive Air Puck Physics Kit includes two pucks with chargers, inelastic collision kit and puck launcher for a complete study of motion. Puck is 7.5" diameter x 2.5" tall. Students love being involved in the setup and operation P4-2150 Air Puck $29.95 of these large-scale, hands-on, minds-on activities! P4-2155 Air Puck Physics Kit $89 The Problem of the Monkey and the Hunter Analysis of the projectile path of the bullet and the monkey’s freefall shows that the bullet will hit the target. But are your students still not convinced? Show them! The “monkey” (a ball) hangs from its “tree” (an electromagnet) up to 4 feet away from the ball launcher (the hunter). Aim the ball directly at the monkey, pull back the plunger, and release. At the instant that the ball is launched power to the electromagnet is interrupted, causing the monkey to fall. Show that the ball will hit the monkey every time provided that the launcher is aimed at the monkey before firing. D battery included. P4-1965 Monkey & Hunter 6 or more $145 $135 Now you can demonstrate this classic discrepant event! 2. Electromagnet releases monkey as hunter fires. 1. Use the sight glass to line up the hunter’s gun. 3. Hunter’s projectile hits the ball (monkey) as it falls. Classic quantitative physics problems come to life with these activities that give students real experience with difficult concepts. SUBSCRIBE TO Releasing Your Potential Pendulum Kit Originally developed for Paul Hewitt’s Conceptual Physics Lab, this apparatus demonstrates key concepts of motion and the transformation and conservation of energy. Load one of the two steel balls in the cup and swing the pendulum. It will strike the horizontal bar and release the ball, which becomes a projectile. Ask students to predict the ball’s range, based on the release height of the pendulum, and place a cup to catch it! PX-4400 Releasing Your Potential Pendulum Kit $39 CoolStuff!
