Question

What statement is true about a spring?

Answer 1

I think B is the most correct, because logically it's harder to bend a stiffer spring than it is to bend a softer one. Also, I don't think length comes into play. So B.

Answer 2

Answer:

B. The stiffer the spring, the greater the force required to restore its position.

Explanation:

The 'restoring force' (the force required to restore the position of a spring) is given by:

$F=-kx$

where

F is the restoring force

k is the spring constant, which determines its stiffness (the higher the value of k, the stiffer the spring)

x is the displacement of the spring relative to its natural length

From the formula, we see that the higher the value of k (so, the stiffer the spring), the larger the restoring force, so the correct option is

B. The stiffer the spring, the greater the force required to restore its position
