Physics 4

What are the differences between Gravitational Potential, & Potential energy? And for electricity?
Which are the formulas where we divide by 'r' and which are the ones where we divide by square of 'r' ?
Also for electricity.

Serious answers only, no stupid jokes and talks, or guesses in here please

 

[Meshuggah]

Wow, no reply.
Anyways, I add: how much marks does Application make up?

 

[pheonix90]

30 out of 100

 

[mista.lova.lova]

gravt potential= GM/R
gpe = GMm/R

 

[Meshuggah]

And I found, Force due to gravity = GMm / square of r
Whats capacitance? Formulas associated with it that are NOT given in the booklet??

 

[Meshuggah]

Some more questions:
1 eV = ? J
And someone please explain M/J 09 9(b)

1 eV = ? J
And someone please explain M/J 09 9(b)

1 eV = 1.6 * 10^-19 J
n sory i dunno about dat ques

 

[imiosa92]

capacitance is the ratio of a charge and its potential. n Newton's law of gravitation is the force between to masses that is indirectly propotional to the square of the distance between the masses

force b/w 2 POINT MASSES. dont loose dat mark

Thanks for those above,
In w07, 4(b), MS says direction is "tangent to curve"
which curve does it mean??
Plus, why is the full-rectified graph made more straight ( ripple reduce) when Resistance is increased?

 

[princesszahra]

any one of the curves given!

 

[Meshuggah]

Im sorry, I get it now,
I was reading Tangent as Normal,
Haha, Maths P3 and Physics P4 in one day !!!

 

[princesszahra]

same here!

 

[Meshuggah]

Haha
Are there many formulas in the applications part?
If there are some do tell them please.

 

[duffer geek]

recheck ur ppr title buddy!!!!!!!!

 

[Meshuggah]

Physics 4, mines 41.
I was wanting to know if there are some formulas in the application part ( Section B).
Never got to study it. Formulas might give a few marks. Rare chance, still.

 

[princesszahra]

uff u never touched it?

 

[Meshuggah]

Haha,
Except now, Im reading the application booklet right now. Feeling sleepy.

 

[asad ali]

any tips as to whats coming in the p4 ??
