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. absurd answers will be reported also....

Answer 1

Answer:

Motion:

1. avg speed =  total distance/ total time taken (v=s/t)

2. avg velocity = initial velocity + final velocity/2 (v = u + v/2)

3. avg velocity = displacement/ time

4. acceleration = final velocity - initial velocity / time (a = v - u/t)

5. v = u + at

6. s = ut + 1/2 * $at^{2}$

7. 2as = $v^{2}$ - $u^{2}$

Force and laws of motion:

1. first law : f = ma or ft = mv - mu

2. second law : f = ma or f = m * v - u /t

3 . third law or conservation of momentum : mAuA + mBuB = mAvA + mbvB

Answer 2

Answer:

5. v = u + at

6. s = ut + 1/2 * at^{2}at
