Question

Can anyone give the all formulas of (chapter 8- motion and 9- force and laws of motion) of science only for class 9 .........right answers will be followed and marked as brainiest plzzzzzzzz answer my Question

Answer 1

chapter 8 motion

speed distance/ time

velocity distance /time

vage total distance/time

vage displacement / time

vinst distance /time

vinst displacement / time

a v-u/t

v u+ at

s ut + 1/2 at^2

v^2 u ^2 + 2as

chapter 9 force and low of motion

F m× a

P m×v

change of momentum mv - mu

Answer 2

Answer:

Ch-8

1. v=u+at

2. S=ut+1/2at²

3. v²=u²+2as

4. v=2πr/t

Ch-9

1. F=ma

2. ∆p=mv

3. m1v1+m2v2=m1u1+m2u2

4. -v=mv/M

5.∆p=F×∆t
