What causes the swinging balls in Newton's Cradle to eventually stop moving?

A) The force of gravity

B) Energy transfer from the balls to the surrounding air

C) Magnetic forces

D) The force from the supporting string

Correct! Wrong!

What is the primary principle demonstrated by Newton's Cradle?

A) Conservation of mass

B) Conservation of momentum

C) Law of inertia

D) Law of universal gravitation

Correct! Wrong!

What material are the balls in a typical Newton’s Cradle usually made of?

A) Wood

B) Rubber

C) Steel or metal

D) Glass

Correct! Wrong!

In a Newton's Cradle, what role does the middle ball play when the first ball is lifted and released?

A) It absorbs the kinetic energy

B) It is the ball that swings the most

C) It remains stationary, acting as a pivot

D) It reflects the energy back to the first ball

Correct! Wrong!

When one ball is lifted and released in a Newton's Cradle, what happens?

A) The opposite ball moves while the other balls remain still

B) All the balls stop moving immediately

C) The entire series of balls move in unison

D) No ball moves

Correct! Wrong!

What happens if you lift two balls on one side of Newton's Cradle and release them?

A) Two balls on the opposite side move

B) Only one ball on the opposite side moves

C) All the balls swing

D) No balls move

Correct! Wrong!

In Newton's Cradle, why do the balls not swing indefinitely?

A) Due to the friction in the air

B) Because they are not perfectly elastic

C) Due to the presence of gravitational force

D) Because they are made of metal

Correct! Wrong!

Which of the following is true about energy transfer in Newton's Cradle?

A) The energy is completely lost after each swing

B) The energy is conserved and transferred through the balls

C) Energy is not transferred but reflected

D) The energy is converted into heat

Correct! Wrong!
