Formulas of ncert class 9 of force and law of motion............. please answer fast

Answered by admin @ 17/08/2021

1. speed = total distance travelled / time required
2.velocity = displacement / time
3.(a) acceleration = change in velocity / time
(b) acceleration = a = final velocity - initial velocity / time
therefore, a = (v-u) / t
4. three equations of motion:-
(a) v = u + at....relation between velocity and time
(b) s = ut + 1/2at square......relation between displacement and time
(c) v square = u square + 2as......relation between displacement and velocity
5. rate of change of momentum = change in momentum / time
( rate of change of momentum = mv - mu / t = m(v-u) / t = ma )

Hope it helps you ✌️❤️✌️❤️
