Question 1
The desk toy Newton's Cradle uses swinging metal spheres to demonstrate what physical principle?
In a closed system, total momentum remains constant. The falling sphere's mass and speed transfer perfectly through the line to the final sphere.
Question 2
A Newton's Cradle reacts how when a user pulls back and drops two spheres on one side?
To conserve both kinetic energy and momentum, the system must eject the exact same mass at the same velocity, meaning two incoming balls push two outgoing balls.
Question 3
The stationary middle balls in a Newton's Cradle serve what physical function during a collision?
Even though they barely move, the central spheres compress slightly upon impact. This acts like a microscopic spring that instantly passes the energy wave forward.
Question 4
Manufacturers make Newton's Cradle spheres out of solid steel to achieve what specific result?
An elastic collision preserves kinetic energy rather than losing it to heat or sound. Steel's high rigidity minimizes deformation, keeping energy in the system.
