In the context of Hooke's Law, what does the spring constant k indicate?

The stiffness of the spring.

The material's elastic limit.

Both A and B.

The amount of force required for a unit displacement.

Which of the following statements about Hooke's Law is false?

The force needed to stretch a spring is proportional to the displacement within the elastic limit.

Hooke's Law applies only when the material is stretched beyond its elastic limit.

Hooke's Law is valid for elastic materials only.

The spring constant is constant for a given spring.

What is the formula for the force required to stretch a spring according to Hooke’s Law?

F = k/x².

F = k/x.

F = kx.

F = kx².

In a situation where a spring is stretched, what does the restoring force depend on?

The displacement of the spring.

The weight of the spring.

The density of the spring.

The material of the spring.

The displacement of a spring is doubled. How is the force affected?

The force is halved.

The force is doubled.

The force is quadrupled.

The force is unchanged.
