With the Newton's Cradle, you can explore concepts such as the conservation of energy, momentum, elastic collisions and friction. Provided with a well…

A Gyroscope is a fascinating mechanical device that at time seems to defy the laws of gravity. The unique characteristic of a gyroscope is that once it is set spinning, it tends to want to remain in its original plane regardless of rotation of its housing. The tendency to resist change in direction…

The Ballistic Pendulum can be used to demonstrate the conservation of momentum with a spring gun, 3 balls with different mass, a pendulum block, and angular scale. Students can calculate the projectile's initial velocity and post-collision kinetic energy. It features an adjustable leveling screw,…

Hooke's Law states that the amount of elongation or bending of a spring is directly proportional to the force that is applied. This unit helps demonstrate this principle. Instructions included. Includes: 1 Sturdy base and rod 1 Testing spring 1 Metal scale 1 Indicator needle 1 Set…
