What else can I help you with?
What is the force that always acts opposite to the direction of the motion?
Friction
What is the force that keeps things floating?
buoyancy
What force in fluid described by Archimedes' principle allow object to float?
Bouyant Force
Is the bouyant force of water proportional to its depth?
No. Water is incompressible. Buoyancy is determined by density, and being incompressible the density stays the same. Once an object is submerged there's no more buoyancy to be generated.
Why centripetal and centrifugal forces are not action reaction pair?
a) Centrifugal force is not even a real force, it is a fictitious force. b) Action and reaction forces act on DIFFERENT objects. If A acts on B, then B acts on A.
What is the force that acts against the force of buoyancy?
The force that acts against the force of buoyancy is gravity. Buoyancy is the upward force exerted by a fluid that opposes the weight of an object immersed in the fluid. Gravity, on the other hand, pulls objects downwards.
What is the name of force that acts in water?
The force that acts in water is called buoyancy. Buoyancy is the upward force exerted by a fluid on an object immersed in it, which opposes the weight of the object and keeps it afloat.
Against what other force does buoyancy act?
Buoyancy is the power to float or rise in a liquid and it acts against the force of gravity.
The contact force that acts on objects in a liquid or gas and allows objects to float is called density or buoyancy?
buoyant force
Is buoyancy contact or a non contact force?
Buoyancy is a contact force that acts on an object submerged in a fluid. It arises from the pressure difference between the top and bottom of an object.
What is the force that acts on any object placed in a fluid?
The forces of gravity and buoyancy both do.
Is buoyancy a contact force?
Contact forces are forces that act at a point of contact between two objects. Buoyant force is an example of a contact force.
What is buoyancy Against what other force does it act?
Buoyancy is the upward force exerted by a fluid that opposes the weight of an object placed in the fluid. It acts against the force of gravity on the object, allowing objects to float or be suspended in a fluid.
What is the main force of boyincy?
The main force of buoyancy is the upward force exerted by a fluid on an object immersed in it. This force is equal to the weight of the fluid that the object displaces. Buoyancy acts in the opposite direction to gravity and helps objects to float or rise in a fluid.
How do the forces of gravity and buoyancy affect a submarine?
The force of gravity acts downwards on a submarine, causing it to sink. Buoyancy, which is the upward force exerted by a fluid that opposes the weight of an immersed object, acts in the opposite direction, helping to keep the submarine afloat or rise back to the surface when necessary by adjusting the density of the water within its ballast tanks. By managing these forces, submarines can control their depth underwater.
The buoyancy force on a submarine submerged in the ocean equals what?
The buoyancy force on a submerged submarine equals the weight of the water displaced by the submarine. This force acts in the opposite direction to the gravitational force, allowing the submarine to float or sink in the water.
What does buoyancy act?
Buoyancy is the upward force exerted by a fluid that opposes the weight of an object immersed in the fluid. It acts in the opposite direction to gravity, pushing objects upwards. This force is what allows objects to float in liquids or gases.
