Newton's Cradle Flashcard

Front

What is Newton's Cradle?

Back

A toy with spheres hanging from a frame that demonstrates energy transfer.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

Why do the spheres in the middle of a Newton's Cradle stay in place?

Back

Because the kinetic energy is transferred to the next sphere in line.

Front

What happens when one sphere is lifted and released in a Newton's Cradle?

Back

The same amount of kinetic energy is transferred to the sphere on the opposite end, causing it to swing out.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

Front

What is an example of Newton's First Law of Motion?

Back

A car coming to a sudden stop and the passengers lurching forward.

Front

What is the role of gravity in a Newton's Cradle?

Back

Gravity pulls the spheres down, allowing them to swing and transfer energy.

Front

What happens to the energy in a Newton's Cradle after several swings?

Back

Some energy is lost to friction and air resistance, causing the swings to gradually decrease.

Front

What is potential energy?

Back

The energy stored in an object due to its position or state.
