Springs and Hooke's Law

What is the formula for Hooke's Law?

If a spring has a spring constant of 200 N/m and is stretched by 0.5 m, what is the force exerted by the spring?

• 50 N

• 100 N

• 200 N

• 400 N

Calculate the spring constant if a force of 150 N causes a spring to stretch by 0.3 m.

• 450 N/m

• 500 N/m

• 150 N/m

• 300 N/m

• The mass of the spring

• The strength of the spring

• The length of the spring

• The gravitational force on the spring

A spring is compressed by 0.2 m and exerts a force of 40 N. What is the spring constant?

• 100 N/m

• 200 N/m

• 300 N/m

• 400 N/m

If the spring constant is doubled, what happens to the force exerted by the spring for the same displacement?

• The force is halved

• The force remains the same

• The force is doubled

• The force is quadrupled

A graph of force versus displacement for a spring shows a straight line with a slope of 300 N/m. What does this slope represent?

• The force applied

• The spring constant

• The change of length

• The initial length

• Newton (N)

• Meter (m)

• Newton per meter (N/m)

• Joule (J)

A spring is stretched by 0.1 m and the force exerted is 30 N. What is the spring constant?

• 200 N/m

• 300 N/m

• 400 N/m

• 500 N/m

If a spring is neither compressed nor stretched, what is the force exerted by the spring?

• Maximum force

• Zero force

• Minimum force
