Projectile Motion - Physics Department

To begin the experiment, a steel ball will be launched from a spring- loaded gun. Once the ball has cleared the barrel of the gun, the force of gravity is responsible for accelerating the ball to the ground. Frictional forces are considered negligible. With this in mind, the motion of the ball can be subdivided into two types: motion

Newton's cradle - Wikipedia

The Newton's cradle is a device that demonstrates the conservation of momentum and the conservation of energy with swinging spheres. When one sphere at the end is lifted and released, it strikes the stationary spheres, transmitting a force through the stationary spheres that pushes the last sphere upward. The last sphere swings back and strikes the nearly stationary spheres, repeating the ...
