Reference: AQA
The inward gravitational force equals the outward pressure from fusion, so the star remains at a constant size.
The state of an object when the net force acting on it is zero, so it is either stationary or moving at a constant velocity.
A state in which the resultant force on an object is zero. This can be static (at rest) or dynamic (constant velocity).
A state in which the resultant force on a single object is zero.
