Motion
(2) Acceleration = change in speed/time = v – u/t
(3) Eq’s o motion
- (a) v = u + at
- (b) s = ut + ½ at2
- (c) v2 – u2 + 2as
Forces
(3) Conservation of momentum, m1u1 + m2v2
Gravitation
(1) Newton’s law of gravitation, force, F = G.m1m2/v2
(2) Acceleration due to gravity, g = GM/R2
(3) Kepler’s 3rd law, T2 = Kr3
- (a) v = gt
- (b) s = ½ gt2
- (c) v2 = 2gs
Flotation
(3) Relative density = s/sw
Work, Energy & Power
(1) Work = force x displacement
(2) Potential energy = mgh
(3) KE = ½ mv2
(4) Power = work/time
Very nice
Very nice
Thanks for this link I have gon 20 marks in my half-year exam these formula was very easy and simple.so thank you
Great to hear! Sneha
Isn’t half yearly of 80 marks?
It is nice site
It would have been better if there was a description on the short forms of the equations like I know that m=momentum but some of the students don’t know that so it would have been better other wise it was helpful ❤
Nice Comment
From which school you are from
Hey Yash i have completed Graduation.
Nalanda
p is momentum, not m
Very nice
These formulas helped me too much.
P is momentum not m
but p=momentum
the genies lady
it’s “genius” not genies
Ya right but students can understand.
Only they have to put their mind whatever they have taught in class.
Gravitation
Newton’s law of Gravitation,force,
F=G Mm/d²
Thank you
SOO GOOd iam iama cry frfr i love it
Very helpful
Thanks for this the basic formulas are clear
It help in exam time .
Thankyou .
This formula sheet is nice.
Thankyou it was really useful
Out of how much ?
Bhai log i have no friends
