Archimedes principal part 1
1. Upthrust
up thrust is a force that generates by a body going through air or a liquid.
simply we can explain "The Force" as a push/pull.
if someone tries to push or pull he also creates a force.
2. so what happens from an upthrust?
while we are in a swimming pool or a Sea, Lake.. we can jump more easily because the water generates a force, water helps us to jump vertically that's the effect of up thrust. so liquids help us to float by giving us up thrust,
3. so why are we still drowning when we bathe a Swimming Pool?
normally our earth tries to pull us to the ground we call it Gravity. that's why we are diving a pool.
But while we are drowning in the pool up thrust trying to push us opposite direction. but most of the times it is not sufficient to keep us float.
4.Are there any places that up thrust can win and make us float?
yeah, there are some places in the world,
ex-dead sea
it has sufficient up thrust to float a man easily in there you can read books while you are reading books. you should thank for up thrust.

5.Is up thrust works on air?
yes of course it is. normally air Planes,Helicopters even birds uses up thrust for there flying.
actually these aircraft birds Knows exactly how to use the up thrust, that's the reason for their flying ability. and also birds have evolved for controlling the up thrust.
6.so how Archimedes connects with upthrust
Archimedes is the mathematician who discovered a principal about upthrust
this is the principal of archimedes
According to Boundless,
"the Archimedes principle states that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid that is displaced by that object. "
lets sort this out
when we put a stone into the water, The stone owns his volume while in the water so the water level will raise
but this is the thing, if we measure this raising water volume and it's mass ,and convert it into it's weight then we have a number,
this number represents the up thrust acting on the stone.
so how do we convert that mass into the weight,we can use this simple formula
weight=mass* acceleration of gravity
if the fluid withdraw/raised 2kg water then the up thrst action on the body is 20N
weight=2kg*10m/s2
=20N
