GCSE Physics - Elasticity, spring constant, and Hooke's Law #44

The video tutorial covers the concepts of elasticity, the spring constant, and Hooke's law. It explains how forces can cause objects to compress, stretch, or bend, and distinguishes between elastic and inelastic deformation. The tutorial also discusses the concept of extension in springs, the role of the spring constant, and how force and extension are related through Hooke's law. The video concludes by highlighting the elastic limit, beyond which Hooke's law no longer applies.

What is the term used to describe an object returning to its original shape after a force is removed?

• Permanent deformation

• Elastic deformation

• Plastic deformation

• Rigid deformation

What is the term for deformation that does not return to the original shape after the force is removed?

• Temporary deformation

• Reversible deformation

• Inelastic deformation

• Elastic deformation

What is the increase in length of a spring when it is stretched called?

• Compression

• Bending

• Extension

• Contraction

What does the spring constant (k) indicate in the context of a spring?

• The length of the spring

• The weight of the spring

• The color of the spring

• The force required to stretch the spring by 1 meter

Which law describes the direct proportionality between force and extension in a spring?

• Newton's First Law

• Archimedes' Principle

• Hooke's Law

• Pascal's Law

What happens to the force-extension graph when the elastic limit is reached?

• The line becomes horizontal

• The line disappears

• The line starts to curve

• The line becomes vertical

What is the relationship between force and extension in a spring according to Hooke's Law?

• Force is exponentially related to extension

• Force is unrelated to extension

• Force is directly proportional to extension

• Force is inversely proportional to extension
