What is the force that acts against gravity?
The force that acts against gravity is the buoyant force.
What is the minimum force to go against gravity?
Any force, however small, can go against gravity.
What is the force that acts against the force of buoyancy?
gravity
What is the upward force that works against gravity?
Any upward force works against gravity,since they act in opposite directions.
What is the force that is working against the buoyant force?
Weight (gravity).

What is the effect of gravity on blood pressure?
It is important to note that the flow of blood in the body is directly influenced by gravity. When a person is standing, gravity helps pull the blood downward to the lower extremities. Without gravity, blood tends to remain closer to the heart. The force of gravity also makes it more difficult for the blood to flow upward to return to the heart and lungs for more oxygen. Our bodies have evolved to deal with the ever-present downward force of gravity; our leg muscles function as secondary pumps to help in the process of venous return which is blood flow back to the heart, also referred to as cardiac input). During walking or other leg movements, the muscles contract, forcing blood up through the veins of the calf toward the heart. The valves in the veins are arranged so that blood flows only in one direction (Figure 10). This mechanism effectively counteracts the force of gravity.
What is the force opisit of gravity?
There is no force opposite to gravity (except in a star where the light pressure from the fusion in the core holds the star up against gravity).
What force acts against gravity in water?
upthrust
What is the force that supports an object against gravity?
traction
