Question

Give all important formulas of class 9 physics..

Answer 1

Speed=distance/time

Velocity=displacement/time

Average speed= total distance/total time

Acceleration =v-u/t

V=u+at

2as=v²-u²

S=ut+ 1/2 at²

p=mv

F=ma

m1u1+m2u2=m1v1+m2v2

F=GMm/d²

Pressure =force/area

Relative density=density of substance/density of water

W=F.s

P.e=meh

K.e=1/2 mv²

Power=W/t
