Which Proportionality Is True When a Force Is Applied to a Spring?

For a given spring and other elastic objects, the extension is directly proportional to the force applied. For example, if the force is doubled, the extension doubles.

What happens to a spring when force is applied?

The extension of a material or a spring is its increase in length when pulled. Hooke's Law says that the extension of an elastic object is directly proportional to the force applied to it. ... if the force applied is doubled, the extension doubles.

Is the extension of a spring directly proportional to force?

extension of an elastic object is directly proportional to the force applied to it. ... At some point the spring will not go back to its original length when you remove the force.
