* No Net Force: The forces acting on the ball perfectly cancel each other out. There's no unbalanced force pushing or pulling the ball in any particular direction.
* Constant Velocity: The ball will either be at rest (not moving) or moving at a constant velocity. This is because a change in velocity (acceleration) requires a net force.
* Possible Scenarios:
* Resting on a surface: The force of gravity pulling the ball down is balanced by the normal force from the surface pushing back up.
* Floating in air: The forces of gravity and buoyancy (air resistance) might be equal and opposite.
* Moving at a constant speed in a straight line: If the ball is moving, any forces acting on it (like friction) are perfectly balanced by other forces (like a constant applied force).
Important Note: Equilibrium doesn't necessarily mean the ball is stationary. It means the ball's velocity is not changing. It could be moving at a steady pace in a straight line.
