Thank you for the clarification.

I am currently brushing on my linear algebra skills when i read this For any Matrix A 1)A*At is symmetric , where At is A transpose ( sorry I tried using the super script option given in the editor and i couldn't figure it out ) 2)(A + At)/2 is symmetric Now my question is , why should it be...

ha ha i got that ...what exactly is your point ? what has that got to do with my question asked? I just said what we speak of work in general is different from the work done in physics.

I am not sure I get your point

Yes it indeed looks that way , this was my thought initially where you use w=F*d when work is done against an opposing force otherwise the change in kinetic energy would be more appropriate.

What Dale is trying to say is for time varying force like that where it is difficult to find the actual displacement (it might be just few x units, but thanks to Newtons law of inertia it will keep on moving ) because the object will move forever thanks to no other force acting on it . It is...

Yes , I Am familiar with the basics of calculus. That does indeed clarify my doubt , thank you :)

Thank you Dale , I am kind of new to this Forum .I am not sure how this forum works yet , so apologies for any inconvenience caused .Coming back to my question , This is what i understood in my high school about work done Example when you push a wall of the room or when you stand in the room...

If I displace an object at rest in space by giving it a force F in X direction and the object tends to move forever, will the work done be infinite? Knowing that work done = force*displacement . Since the space has no external resistance (unbalanced force) to stop the object from moving , making...
