Discuss on law of physics studies and its applications in daily life
Answers
solution : physics is nothing but the study
of the nature and properties of matter and
its energy. so it's obvious that every law of
physics has importance in our daily life.
there are hundreds of laws of physics but
if you asked me only one to explan with its
application in our daily life, i must consider
Archimedes' principle.
Archimedes' principle: it is one of the
most important fundamental law of physics
which helps us to find the volume of object
of irragular shape, helps to make ship and
boat and find the density of object.
when a object is partially or fully
submerged in a liguid. an upward force
(known as buoyant force) acting on the
body which is equal to the weight of liquid
displaced by the object. "
this buoyant force, F =pVg
where p is the density of the liquid, Vis the volume of displaced liquid and g is acceleration due to gravity.
application of Archimedes' principle :
1. this principle is used in designing the ships and submarines.
2. lactometer which is used to measure
the purity of milk is based on Archimedes' principle.
3. hygrometer which is used to measure the density of liquid, is also based on Archimedes' priniciple.
