EXPLORE GRAVITATIONAL POTENTIAL ENERGY || Medieval weapons, engineering, and physics - not a bad classroom learning activity, or way to spend a Saturday afternoon. This trebuchet which will throw the included ping pong ball more than 30 feet (or heavier objects even farther!). This kit allows...
Helmholtz coils are useful for creating near-uniform magnetic fields or for cancelling out external magnetic fields, such as the earth’s. The field between the two solenoids is at its most uniform when the distance between them is equal to the radius of the solenoids. This can also be used with a...
