An object in water ... whether floating or completely submerged ... is acted upon by two forces in the vertical direction: 1). its weight, directed downward, equal to its (mass) times (acceleration of gravity) 2). its buoyancy, directed upward, equal to the weight of the water that it displaces

What 2 forces act on a object in water?
Two forces that act on an object in water are buoyant force, which pushes the object upwards, and gravity, which pulls the object downwards.
Is weight an upthrust?
Weight is a force acting downwards on an object due to gravity, while upthrust (buoyant force) is a force acting upwards on an object immersed in a fluid. These two forces act in opposite directions but are not the same. Weight depends on the mass and gravity, while upthrust depends on the volume of the object displaced in the fluid.
When a submerged object is in water that forces are acting on the object?
When a submerged object is in water, forces such as buoyancy (upward force due to displacement of water), gravity (downward force due to the object's mass), and drag (resistance force due to the object's motion) act on it. These forces determine the object's behavior and whether it sinks, floats, or remains suspended at a certain depth.
Why does bouyant force act upward on an object submerged in water?
The buoyant force acts upward on an object submerged in water because of the difference in pressure between the top and bottom of the object. The pressure at the bottom of the object is higher than at the top, resulting in a net upward force on the object. This force is equal to the weight of the water displaced by the object, pushing it upward.
At what point on an object is the force of gravity considered to act?
The force of gravity is considered to act at the center of mass of an object.
What 2 forces act on a object in water?
Two forces that act on an object in water are buoyant force, which pushes the object upwards, and gravity, which pulls the object downwards.
What kinds of forces can act on an object?
Normal force can act on an object

Why does buoyant force act upward?
The buoyant force on an object submerged in a fluid is caused by the pressure difference between the top and bottom of the object. To overcome the gravitational force, the buoyant force acts in the upward direction. The larger pressure at greater depth pushes upward on the object.
Is weight an upthrust?
Weight is a force acting downwards on an object due to gravity, while upthrust (buoyant force) is a force acting upwards on an object immersed in a fluid. These two forces act in opposite directions but are not the same. Weight depends on the mass and gravity, while upthrust depends on the volume of the object displaced in the fluid.
When a submerged object is in water that forces are acting on the object?
When a submerged object is in water, forces such as buoyancy (upward force due to displacement of water), gravity (downward force due to the object's mass), and drag (resistance force due to the object's motion) act on it. These forces determine the object's behavior and whether it sinks, floats, or remains suspended at a certain depth.
At what point on an object is the force of gravity considered to act?
The force of gravity is considered to act at the center of mass of an object.
What is the only force that can act on an object in free fall?
The only force that can act on an object in free fall is gravity.
Why does bouyant force act upward on an object submerged in water?
The buoyant force acts upward on an object submerged in water because of the difference in pressure between the top and bottom of the object. The pressure at the bottom of the object is higher than at the top, resulting in a net upward force on the object. This force is equal to the weight of the water displaced by the object, pushing it upward.
When you lift an object up two forces act on it identify these forces?
When you lift an object up, the two forces acting on it are the force of gravity pulling it down and the force exerted by you to lift it up. The force of gravity is acting downwards on the object, while your force is acting upwards against gravity to lift the object.
Why does the buoyant force act upwardon an object submerged in water?
The buoyant force acts upward on an object submerged in water due to the difference in pressure between the top and bottom of the object. Pressure increases with depth in a fluid, so the pressure at the bottom of the object is greater than at the top, resulting in a net upward force. This force helps keep the object afloat.
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.
