Question

WHAT ARE THE FROMULA USED IN CLASS 9 PHYSICS

Answer 1

hey dude!!!!

there are many formula's used in class 9th physics :-

average speed :

$\frac{total \: distance}{total \: time}$

velocity:

$v = \frac{s}{t}$

acceleration:

$a = \frac{v - u}{t}$

momentum:

${p = m \times v}$

principle of conservation of momentum:

$m1u1 + m2u2 = m1v1 + m2v2$

energy:-

kinetic energy:

$\frac{1}{2} \times m {v}^{2}$

gravitational potential energy :

$mgh$

power :

$p = \frac{w}{t}$

$p = \frac{e}{t}$

Hooke law:

$f = kx$

density:

$\frac{m}{v}$

hope this helps you
