Gaussian Gun
Show how one ball starting at rest can gain enough energy to hurl another across the room.
Supplier: Science First 6111705
Includes: Four neodymium magnets, four magnet holders, 10 steel balls, low-friction metal track with open end for launching balls and instructions with theory
Description
Study projectile motion as well as conservation of energy and momentum. Investigate the properties of magnetism.
- Four magnets and 10 steel balls are aligned on a low-friction linear track
- A slowly rolling ball at the far end of the track is pulled forward by magnetic force
- Accelerated to three or four times its original speed, the ball collides with a pair of balls set further down the track
- The second ball is propelled outward; attracted by the second magnet, the second ball sends a third ball careening even faster
- When this happens four times in a row, the last ball flies free
Order Info
Balls: 0.75 in. dia. (1.9cm).
