SUMMARY

The discussion centers on the net force acting on a mass attached to a stretched spring in a state of equilibrium. The primary forces identified are gravitational force and the spring's restoring force, which act in opposite directions. When the mass is motionless, the net force is zero, indicating that these forces are balanced. This conclusion aligns with Newton's First Law of Motion, confirming that an object at rest remains at rest when the net force is zero.

PREREQUISITES
  • Understanding of Newton's Laws of Motion

1. A mass is attached to a stretched spring and hangs motionless. What forces act on the mass? What is the net force?

I think that the forces are gravity and the springs restoring forces, but I am not sure which way the net force is? What is the net force?

Well, if the mass is motionless, that means it's at rest. What does this tell you about the net force?
