Hooke's Law and Spring Energy Review

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

Which of the following springs is the stiffest?

• A spring that requires a froce of 2000 N to compress it by 6.8 m.
• A spring that requires a force of 4000 N to stretch it by 9.0 m. 
• A spring that requires a force of 8000 N to compress it by 45 m.  
• A spring that requires a force of 4800 N to stretch it by 14 m.

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

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

A graph of force vs. distance 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 the Earth's gravitational field strength (g) is 10N/kg, how much weight does a 1kg mass (m) have in Newtons?
F =m x g

• 100g
• 10N
• 1N
• 1000N
