Does a object, that is partially submerged in a liquid, lose any weight?
I know that all objects, regardless of their density, feel buoyancy force. But do partially submerged, meaning an object that has lesser density than the liquid,lose weight.
For example and object ...

Does Weighing machine measure normal force or gravity or both?
A weighing machine measures the normal force applied by an object.
However 2 forces act simultaneously on the machine ( normal and mg )
Under normal conditions (a=0) N=mg .
So this would mean that a ...

If an object suspended by a string is immersed in a liquid, will its weight contribute to the pressure at the bottom of the container?
We have a metal sphere completely immersed in a liquid of density A by means of a string.
Since the sphere is exerted by the buoyant force due to the liquid the sphere must also exert an equal and ...

Is the weight of something being dropped the same as the force of something being static?
If I have a block of let's say: 10 kg and I put it over my foot in a static manner, what we know from static mechanics is that my foot is opposing the weight of the 10 kg mass with the same force in ...
