Force & Motion Classic and brand new demos and activities will build student understanding of fundamental physics concepts! Newton would have loved this discrepant event! Using a double sided ramp and a series of steel marbles, you initially demonstrate Newton’s First Law by rolling one steel marble down the ramp to collide with a resting group of marbles. Not so impressive so far… While setting up to repeat the demo, replace the first resting steel marble with a magnetic sphere. Your students will be amazed as the collision shoots the last steel marble right off the ramp! P4-1365 Magnetic Accelerator $19.95 Is energy conserved in a magnetic field? Watch as students try to figure out this amazing demo. Use a little drama and slight-of-hand to generate thoughtful discussion of conservation laws! visit arborsci.com > > > FREE Product Demos!

Bouncing Dart Originally developed for Paul Hewitt’s Conceptual Physics, the Bouncing Dart demonstrates the energy transformations that occur in elastic and inelastic collisions. The dart has an elastic end and an inelastic end. Swing the dart so that it collides with a massive (1 kg or more) dynamics cart, and compare the distances the cart moves when hit by the different ends. Investigate auto body features such as crumple zones. Add an accelerometer to see changes in the cart’s acceleration. Also required: Two 3/8 inch ring stands or other supports Recommended: Dynamics Carts (next page) PX-1204 Bouncing Dart $24 6 or more $22 Download the newest lab activities for Paul Hewitt’s Conceptual Physics, now at www.arborsci.com. Vertical Acceleration Demonstrator The Vertical Acceleration Demonstration is one that no beginning physics student should miss. It dramatically demonstrates a concept that is crucial for understanding projectile motion: that the acceleration due to gravity only affects an object’s vertical motion. Two balls are mounted on the apparatus. When you release the spring, one is dropped directly down while the other is projected horizontally. Listen, and you’ll hear that both hit the floor at the same time! Easy to set up and level. A Rod Clamp and Ring Stand are required items.

Dropped from the roof of a building, which would hit the ground first? …too gross to think about, but your students will love it! Much easier to demonstrate and economically priced, our Coin & Feather Demo can be used to perform the classic experiment of a lighter object falling at the same rate as a heavier object when resistance is removed from the equation. The demo includes a metal disk, a feather and a transparent freefall tube. The tube easily mounts on a ring stand or can be held by a student. The tube is 100 cm The Hand-held Vacuum Pump long and 3.5 cm in diameter generates a and is equipped with an vacuum of evacuating valve. Any standard 30 in. Hg. vacuum pump can be attached, or use our hand-held vacuum pump. P1-5200 Coin & Feather Demo $39 P1-5201 Hand-held Vacuum Pump $33 Classic Vector Demo! 16 1-800-367-6695
