Elasticity and Hooke's Law Quiz

What happens to an object when it returns to its original shape after the forces are removed?

• It remains permanently deformed.

• It breaks into pieces.

• It undergoes elastic deformation.

• It undergoes plastic deformation.

What is the term used to describe the increase in length of a spring when it is stretched?

• Extension

• Deformation

• Bending

• Compression

What force acts on a spring due to its own mass?

• Compression

• Weight

• Tension

• Elastic force

What does the spring constant (k) measure?

• The length of the spring

• The time taken to stretch the spring

• The mass of the spring

• The force required to stretch the spring by one meter

In the equation F = k * e, what does 'e' represent?

• Energy

• Force

• Spring constant

• Extension

What does a straight line passing through the origin in a force-extension graph indicate?

• The spring is inelastic.

• The spring has reached its elastic limit.

• Force and extension are inversely proportional.

• Force and extension are directly proportional.

What is Hooke's Law?

• Force is inversely proportional to extension.

• Force is directly proportional to extension.

• Force is independent of extension.

• Force is equal to the spring constant.

What happens when the elastic limit of a spring is exceeded?

• The spring returns to its original shape.

• The spring undergoes elastic deformation.

• The spring undergoes inelastic deformation.

• The spring breaks.

What is another term for inelastic deformation?

• Elastic deformation

• Plastic deformation

• Permanent deformation

• Temporary deformation

What is the significance of the limit of proportionality in a force-extension graph?

• It marks the point where Hooke's Law no longer applies.

• It shows the spring's natural length.

• It indicates the maximum force the spring can handle.

• It represents the spring's breaking point.
