MOMENTUM & PRESSURE :star: - Coggle Diagram
MOMENTUM & PRESSURE :star:
Physical quantity
Scalar quantity
Derived quantity
Pressure in Liquids
P= ρgh
Pressure is more with more depths
Pressure is more with more gravity
Pressure is more with more denser liquid
Pressure in liquid properties

Pressure in Solids
Pressure in solids
P= F/A
More Force involves more pressure
Pressure is inversly proportional to area
Pressure is directly proportional to force.
Less area involves more Pressure

Momentum is vector whereas pressure is scalar quantity
Both are Physical quantities fall in derived quantites.
Impulse
vector & derived quantity
Impulse= mv-mu
Units=kgm/s=Ns
Impulse=F*t
Product of force and time for how long the force has been applied
Law of conservation of Momentum
In an isolated system, the total initial momentum of the system equals to total final momentum of the system.
m1u1+m2u2 = m1v1+m2v2
m1= mass of 1st object
m2= mass of 2nd object
u1= initial velocity of first object
u2= initial velocity of 2nd object
v1= final velocity of first object
v2= final velocity of 2nd object
Isolated system is the one where no external force acts on the system.

Derived & vector quantity
p = mv
Units= kgm/s = Ns
Quantity of motion of an object
