TED-Ed: Would you weigh less in an elevator? - Carol Hedden

The video explores the physics of an elevator in free fall, examining forces acting on a person standing on a scale inside it. It explains how gravity and the normal force interact, using Newton's second law to describe equilibrium and changes when the elevator accelerates. The video also discusses the effects of jumping inside a falling elevator and considers scenarios like upward acceleration and cable failure.

Explain the concept of normal force in the context of standing on a scale.

What would occur if the elevator were to accelerate upward suddenly?
