How newtons cradle balance balls work
newtons cradle balance balls
The newtons cradle balance balls have been remodeled many times, but the basic silhouette remains the same, very simple. An odd number of balls (usually five or seven) that barely touch hang on a wooden or metal frame. Balls are usually made of stainless steel and in rare cases titanium. Due to its good elasticity and low price, stainless steel is an ideal material for ball structures.
Each ball has the same properties (size, weight, mass and density) and is suspended by two lines of equal length. Lean from either side of the wireframe to form an inverted bottomless triangle with the ball. They also help limit the pendulum's motion to a single plane parallel to the frame bars.
The operation of the newtons cradle balance balls is as simple as its construction. When the ball at one end is lifted and released, it hits the next ball at rest and transfers all its energy to it. Through a series of incredibly fast passes, energy is transferred to the ball at the other end, forcing the ball to swing up. The terminal ball rises to the same height as the first ball, then descends to hit the stationary ball. Now, both energy and motion are going in opposite directions, and finally the first ball is pushed out again. The subsequent process continues until all the energy transferred at the beginning is lost by air resistance, acoustic energy, and any heat generated between the vibrating spheres.
