this is a learning forum...anyone can participate...but not the persons who don't have minimum manners like u... finally its not the knowledge that counts...its the character. i guess there should be a separate forum to elighten people like u... And for ur kind information... i said pressure...

could anyone explain me the Newton's second law of motion in detail? It tells that rate of change of momentum is equal to force applied. what does it physically mean in real applications? is it like force is causing the change in momentum or is it like if there is a change in momentum, a...

If u see dynamic pressure, they say it is the force exerted by the fluid(over an area) using its bulk K.E. Dyn pressure= V2/2g. where V= bulk velocity of fluid Likewise, what is static pressure? what is the energy that is responsible for static pressure? i was told that it is the average...

if static pressure is due to gravitational pull, then why there r separate terms for gravity and static pressure in bernoullis equation? please explain

thank u sir Now, how do u define that pressure force? like for eg, if u say gravitational force, it is the force by which Earth is attracting a body. likewise, what is the source for a static fluid to exert a force, which we call as pressure? is it the kinetic energy of molecules? if so, wat...

then wat abt open channel flow where pressure is atmospheric evrywhere

that was great participation from all of u...i learned a lot we shall continue this discussion further... i mean with related concepts...as of now, i am reading abt energy and laws of motion, properties of matter etc...i will come up with doubts in short time...dont go anywhere..pleasez

yes atty, this is what i understood from all of ur explanation and i am putting it in proper order below... A body has some amount of energy associated with it, which would be either in the form of potential energy or kinetic energy. Energy flows from one body to other in the form of work or...

recently i was asked one question in an interview! How fluids flow? i mean whether it is because of pressure difference or any other reason. one more thing! could anyone explain me what is actually the pressure of a fluid and what is the gravitational force exerted on fluid(i.e weight, as i...

thanks adriank, that was great explanation. now its very clear... Now let's move onto next topics... what r the factors that make the energy flow from one body to other body? As we see, in this universe, there r different bodies with different(both in quantity and type) energies associated...

thats an amazing response from all of u...thank u... Now can i take like this... Energy is of two types, energy in transit(work,heat,mass) and stored energy(all other forms). Every body(matter) will have some amount of energy associated with it(stored energy), by which it is capable of doing...

Hi, i want to intiate the discussion on energy?Although its a very basic and general topic, i request u all to participate to study it thoroughly... how do u define energy? According to common definition given by all, it is the ability to do work. But work is also a form of energy. So i...

i am an engineering graduate. i have a special interest in physics. After my school, i never touched physics. could anyone suggest me a book best for physics,please? It should cover all the general physics concepts in detail and easily understandable. It should act as a ALL IN ONE for me...

could anybody suggest me a book on fluid mechanics which provide strong basics as well as detailed knowledge thanks
