SCIENCE GIZMOS: Magnetic Accelerator
Materials supplied: 1x Track, 2x wooden blocks, 5x metal spheres (2.0 cm), 1x magnetic metal sphere (2.0 cm). Safety glasses recommended, but not provided. Note: Track has several different orientations: straight; raised 4.0 cm on either or both ends; and raised 6.0 cm on either or both ends.
How does this activity demonstrate the Law of Conservation of energy? Roll a metal sphere slowly into three spheres resting centrally on a horizontal track with ends touching each other. Watch as the last sphere takes off with increased velocity showing the the system somehow has gained energy!
Science Gizmos are fun and easy to use. See how to demonstrate the properties, mechanics and applications used and taught in Physics and Chemistry labs.
