gravity
Weight is the magnitude of the force caused by the interaction between an object's mass and the net gravitational field the object is resting in.
The weight of an object is the force of gravity.
The downward force exerted on an object is caused by gravity (from the Earth). This force is called weight and can be calculated by multiplying the mass of the object by the acceleration due to gravity on Earth (about 9.8).
If the object is floating, then the buoyant force is equal to the object's weight.
If the object is floating, then the buoyant force is equal to the object's weight.
The upward bouyant force depends only on the weight of the displaced fluid. The NET force (object's weight - bouyant force) depends on the object's weight and will determine how fast it sinks.
If the object is floating on the surface of the fluid, like a boat, then the fluid is exerting the normal force on the object. The normal force is a force that is equal and opposite to the force of gravity acting on an object. If the object is under the water then the weight of the water above the object is pushing down on it.
weight, The weight of an object is the force of gravity acting on it.
An object floats when the buoyant force is equal to the object's weight. An object sinks when the buoyant force is less than the object's weight.
Weight is the measurement of gravitational force on an object, relevant to Earth.
The force of gravity between the Earth and an object on its surface is what we call the object's "weight". What is not generally appreciated is that the object attracts the Earth toward it with the same force. This means that whatever your weight is on Earth, it's the same as the Earth's weight on you.
Mass and Weight The gravitational force Earth exerts on an object is the weight of the object. Because weight is a force, it is measured in newtons. Weight is not the same as mass. Mass is the amount of matter an object contains, and is measured in kilograms. Even if the mass of an object doesn't change, its weight will change if its distance from Earth changes
