Hooke's Law and Elasticity Quiz

What does Hooke's law describe?

• The relationship between force and extension in elastic objects

• The relationship between mass and acceleration

• The relationship between velocity and time

• The relationship between energy and power

What is the formula for Hooke's law?

• P = W / t

• E = m * c^2

• F = k * e

• F = m * a

In Hooke's law, what does the symbol 'k' represent?

• Spring constant

• Extension

• Mass

• Force

What is measured in newtons per metre (N/m) in Hooke's law?

• Extension

• Spring constant

• Force

• Mass

What happens when a material is stretched beyond its elastic limit?

• It returns to its original shape

• It breaks immediately

• It becomes inelastic

• It becomes more elastic

What is the limit of proportionality?

• The minimum extension a spring can have

• The point beyond which Hooke's law is no longer true

• The point where force equals mass times acceleration

• The maximum force a spring can withstand

What is the unit of force in Hooke's law?

• Newtons

• Watts

• Joules

• Meters

If a spring has a spring constant of 20 N/m and is stretched by 0.15 m, what is the force applied?

• 0.3 N

• 1.5 N

• 3 N

• 30 N

What type of deformation occurs when a material does not return to its original shape after the force is removed?

• Non-linear deformation

• Linear deformation

• Plastic deformation

• Elastic deformation

What does a higher spring constant indicate about a spring?

• It is longer

• It is more elastic

• It is less stiff

• It is stiffer
