Question

Why is the restoring force in Hooke's law a negative value?

A. The force is opposite the displacement.
B. The force is smaller than the displacement.
C. The force is larger than the displacement.
D. The force is in the direction of the displacement.

Answer 1

A

Step-by-step explanation:

Answer 2

The spring force is called a restoring force because the force exerted by the spring is always in the opposite direction to the displacement. This is why there is a negative sign in the Hooke's law equation. Pulling down on a spring stretches the spring downward, which results in the spring exerting an upward force.
