so when moving in same direction of gravitational attractive force in gravitational field this is negative WD and when moving in opposite direction to gravitational attractive force workdone is positive??
It depends whether we are talking about work done by the field, or work done by external force! The one you described is 'work done (by external force)'
Thank you so much! This cleared up all my confusions related to gp
Thank you very much
Amazing explanation!!
Tq ms eli
All the best in learning physics! -Ms E
omgggg i love u so much u made this so much easier
8:09 as u were integrating it i just wanna know what happened to d with the r??
Amazing teacher

@@ETphysics thanks for the info
Hi!! Can you say “work got out as the mass moves from infinity to a point”????
Yes, you can say that too!
Thank you mam
😍😍😍
Maam why do we assume that g.p is zero at infinity???
I think it is only a choice to make it 0 instead of something like "maximum potential", but infinity itself is a very vague idea

You don't need to know integration for A level physics right?
According to my teacher you don't need integration or any A Level maths. But basic algebra (like from igcse) is pretty important.
yeah, i dont think you need integration for A-Level Physics, but you do need it for A-Level Math
