Edexcel PHYSICS Doubts

[S.M.A.T]

Just to clarify, the two are different forces because one is not a cause of the other...

Well you can say that.
The thing is that here F-1 is contact force and F-2 is gravitational force.

Yup that's how it is i suppose.

Thanks asif

the gravitational force 'F' between 2 masses M1 and M2 separated by a distance 'r' is given by the formula F = G(M1M2/r²) where 'G' is the universal gravitational constant.
Determine the base units of 'G'.

pls explain how do i go about this question
Thanks

F= Newtons = ma = Kg*M/s^2
M=kg
r=radius =M

F= GM1M2/r^2
G=F*r^2/M1M2
=NM^2/Kg^2
or
M^3/(Kg*s^2)

[haris94]

o i get it
u hv to make G the subject of the formula
i wasnt aware of that

Thanks again

u r welcome

in newton's Second Law of Motion  , the teacher gave us two cases ;

case 1 :
acceleration is directly proportional to resultant force when Mass is CONSTANT

case 2 :
acceleration is Inversely proportional to Mass when Force is Kept CONSTANT

and he gave an experiment  for both cases  ,can some one give me good notes/site which explains it in detail (cuz i  need it to FULLY understand it )

Thx

I have to go for now but i'll came perhaps tmrrw iA

Thx loads man it really helped  ..I'd really appreciate it if u had notes/site that emphasize on the experiments as well

I think I can help you there. If you email paul.smith@astarmathsandphysics.com I will email you back a set of 50 or so experiments with notes

Hey Everyone ...Well I have a Doubt .....Can someone give me notes or a Website that has notes on Fluid Flows ...The teacher just taught us some of the basics And the whole time I was -__-  cuz i didn't get it :S :S

Thank You In Advance
