Differences between gravitational forse and buoyant forse
Answers
answer: force is something which creates a change in state or size of a substance.
Explanation:
Gravitational force is the force exerted by the earth on a body .
it acts vertical downwards .
It's SI unit is g/cm⁸.
buoyant force is the force which a body experiences when it is submerged in water .
It acts vertically upwards.
Question
Differences between gravitational forse and buoyant forse
Answer
The gravitational force can be thought of as a force pulling you “down” (to the earth's centre of mass). This force is proportional to the mass of the object divided by the inverse square of it's centre of mass from you.
The buoyant force can be thought of a force that is pushing upwards equal to gravity. This force isn't very applicable in minor cases. But in a larger scale it can come in very useful.
One way this is exploited is by using boats. Boats are actually lighter per cubic metre then water and are shaped to keep the surface tension.
