Hooke's Law

A spring has a spring constant of 330 N/m.  How far is the spring compressed if 150 N of force are used?

• 2.2 m
• 0.0014 m
• 5.0 m
• 0.45 m

A force of 470 N is applied to stretch a spring which has a spring constant, k=1100 N/m.  How much does the spring stretch past its free length?

• 0.214 m
• 2.34 m
• 0.427 m
• 5.17 X 10^5 m

What force should be applied to compress a spring by 0.013 m if its spring constant is k = 1900 N/m?

• 1880 N
• 24.7 N
• 1900 N
• 0.127 N

A force of F=500 N is applied to extend a spring.  What is the displacement x of the spring if its spring constant is k= 540 N/m?

• 0.96 m
• 0.93 M
• 1.3 m
• 1.1 m

A net force of 430 N acts to stretch an extension spring.  How far will the spring stretch if its spring constant is 700 N/m?

• 43.9
• 0.307 m
• 1.63 m
• 0.614 m

What Quantity can you calculate from the graph and give the magnitude of that quantity.  

• distance 4.5 m
• Force 15 N
• spring constant 20 N/m
• spring constant 200 N/m

A spring has a spring constant of 5N/cm.  What is its extension when loaded with 15N?

• 4cm
• 5cm
• 3m
• 3cm

Hooke's Law describes the behaviour of which kind of material under tension?

• plastic
• metals only
• elastic
• non-metals only

If F is force, k is spring constant and x is extension, Hooke's Law tells us that:

• F=k/x
• x=Fk
• k=Fx
• F=kx

A stiff material has a:

• high spring constant
• low spring constant
• spring constant of any value
• spring constant which is difficult to predict
