A spring extends 1.5m under load 10N. What is its spring constant?

• 0.15N/m

• 10N/m

• 6.7N/m

• 15N/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

A 25,000 N Car is supported by 4 springs. If each spring is deflected by 0.040 m what is the spring constant? (Think about how much weight each spring holds up!)

• 160,000 N /m

• 620,000 N/m

• 630,000 N/m

• 120,000 N/m

Spring constant is measured in

• N

• N/m

• m

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

Which statement most accurately represents Hooke's Law?

• Extension of a spring is proportional to the number of coils

• Thickness of a spring wire is proportional to the force applied.

• Extension of a spring is proportional to the force applied.

• Extension of a spring is inversely proportional to the force applied.

A net force of 1400 N acts to stretch an extension spring. How far will the spring stretch if its spring constant is 700 N/m?

• 0.5m

• 1.5 m

• 2.0 m

• 1.0 m
