Which of the following best describes the restoring force in simple harmonic motion?

• A. It is proportional to the object's speed
• B. It is always directed towards the equilibrium position
• C. It increases with distance from equilibrium
• D. It does not depend on displacement

Answer: (B)

The restoring force in simple harmonic motion is best described as always directed towards the equilibrium position. In this type of motion, the system seeks to return to its equilibrium state after being displaced. When an object is moved from its equilibrium position, a force is generated that acts in the opposite direction of the displacement. This characteristic force is what brings the object back toward the equilibrium point, resulting in oscillatory motion. Additionally, while it's true that the restoring force can increase with distance from the equilibrium (as indicated by the principle of Hooke's Law for springs), the defining trait is its directionality toward the equilibrium position, which is the key characteristic of simple harmonic motion. This directional nature helps ensure that when the object is pulled further away, the restoring force becomes stronger, thereby increasing the acceleration towards equilibrium. In summary, the crucial aspect of the restoring force in simple harmonic motion is its consistent direction towards the equilibrium position, ensuring that the system oscillates in a stable manner around that central point.
