Newton Cradle: How it works?

What fundamental physics principles are demonstrated by Newton's Cradle?

• Conservation of mass and volume

• Conservation of momentum and energy

• Conservation of force and acceleration

• Conservation of temperature and pressure

In its initial state, when one or more metal balls are lifted on one side of Newton's Cradle, what type of energy is stored?

• Kinetic energy

• Thermal energy

• Potential energy

• Chemical energy

According to the principle of conservation of momentum, what happens to the total momentum of an isolated system like Newton's Cradle if no external forces act on it?

• It increases over time.

• It decreases over time.

• It remains constant.

• It fluctuates randomly.

When a lifted ball is released and collides with the stationary balls, how is the energy transmitted through the chain?

• It is absorbed by the stationary balls and converted to heat.

• It is transferred through the chain of balls, causing the last ball to swing upward.

• It causes all the stationary balls to swing simultaneously.

• It is lost due to air resistance and friction.
