What is neutral buoyancy?
When gravitational force equals the buoyant force and object is suspended in the fluid.
25
What is positive buoyancy?
When buoyant force is greater than gravitational force.
26
What is negative buoyancy?
When the buoyant force is less than the gravitational force.
27
What is average density?
The total mass of an object divided by the total volume.
28
What is a hydraulic system?
