The Human Spine acts like a Compression Spring

The video tutorial explores the physics of springs, focusing on calculating the spring constant of a horizontal spring system. It explains the forces involved, including gravity's effect on spring length, and compares this to the human spine's behavior under gravity. The tutorial concludes with a discussion on the potential health implications of spinal compression and expansion, especially in space environments.

What is the mass of the object attached to the cord in the problem?

• 0.1 kilograms

• 0.5 kilograms

• 0.045 kilograms

• 0.025 kilograms

Which law is used to solve for the spring constant in the problem?

• Newton's Third Law

• Newton's Second Law

• Newton's First Law

• Law of Universal Gravitation

Why is the force of gravity not included in the free body diagram for the spring?

• It is negligible.

• It only causes the spring to curve slightly.

• It acts in the same direction as the spring force.

• It is balanced by another force.

What type of spring is designed to be expanded?

• Expansion spring

• Torsion spring

• Compression spring

• Leaf spring

How does the length of a compression spring change when it is vertical?

• It becomes longer.

• It remains the same.

• It becomes shorter.

• It twists.

What happens to the human spine when standing compared to lying down?

• It twists.

• It becomes longer.

• It remains the same length.

• It becomes shorter.

• Up to 4%

• Up to 3%

• Up to 2%
