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

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

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

Hooke's Law fails when a material reaches:

• breakdown
• its elastic limit
• end of its tether
• fracture stress

Hooke's law describes how as the force increases the rate of increase of ............ is the same.

• the length of a spring
• gravity
• the extension of a spring

A graph of extension against force for an elastic material is:

• A downward curve
• An upward curve
• A straight line from any point on the x and y axis
• A straight line from the origin

If extension = Stretched length - original length. What is the extension of spring D.

• 1mm
• 2mm
• 3mm
• 0mm

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
