Physics of Springs Quiz

What is Hooke's Law?

• Hooke's Law states that the force needed to extend or compress a spring by some distance is unrelated to that distance.

• Hooke's Law states that the force needed to extend or compress a spring by some distance is inversely proportional to that distance.

• Hooke's Law states that the force needed to extend or compress a spring by some distance is only applicable to certain types of springs.

• Hooke's Law states that the force needed to extend or compress a spring by some distance is proportional to that distance.

What is the formula for Hooke's Law?

• F = k/x

• F = -kx

• F = x/k

• F = kx

What does 'k' represent in Hooke's Law?
