Formulas of ncert class 9 of force and law of motion............. please answer fast |
|
Answer» d = total distance travelled / TIME required2.velocity = displacement / time 3.(a) acceleration = change in velocity / time(B) acceleration = a = FINAL velocity - initial velocity / time therefore, a = (v-u) / t4. 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 velocity5. 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 ✌️❤️✌️❤️ |
