Hooke's Law

What type of deformation occurs when an object returns to its original shape after the applied forces are removed?

• Inelastic deformation

• Plastic deformation

• Elastic deformation

• Permanent deformation

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

• Compression

• Tension

• Extension

• Deformation

• Yes

• No

In the equation F = ke, which describes the relationship between force (F) and extension (e) for a spring, what does 'k' represent?

• The object's mass

• The object's stiffness

• The object's length

• The object's weight

What happens to an object when the applied force exceeds its elastic limit?

• It becomes stiffer and harder to stretch.

• It undergoes inelastic deformation and may not return to its original shape.

• It returns to its original shape more quickly.

• Hooke's Law continues to apply, but with a different spring constant.
