About the physical buoyancy, how to judge that the buoyancy is greater than the gravity, buoyancy is the same as gravity

When an object is still or rising at a constant speed in water, buoyancy is equal to gravity. If the buoyancy is greater than gravity in accelerating or decelerating rise, the buoyancy is less than gravity in accelerating or decelerating rise
