g is constant, but Fd/m is reduced, I see it now :D thanks.Bandersnatch said:You've got ##a=g-F_D/m##. (minus is up here) If you increase mass, g is reduced more or less?
According to the laws of physics, an object's acceleration due to gravity is directly proportional to its mass. This means that the heavier the object, the greater its gravitational force and the faster it will fall in a liquid medium.
Yes, the density of the liquid does affect the speed at which a heavier sphere falls. The denser the liquid, the more resistance it will provide against the falling object, resulting in a slower speed.
The shape of the sphere does not have a significant impact on its falling speed in a liquid. The main factors that affect the speed are the mass and density of the sphere and the density of the liquid.
Yes, the viscosity of the liquid does play a role in the falling speed of a heavier sphere. The higher the viscosity of the liquid, the more resistance it will provide against the falling object, resulting in a slower speed.
No, according to the laws of physics, a heavier sphere will always fall faster than a lighter sphere in a liquid medium. This is because the heavier sphere has a greater gravitational force and experiences less resistance from the liquid.
