State Newton's second law of motion. Der ve F=ma |

Answer» ong>Answer: Newton’s second law of MOTION states that the force exerted by a body is directly proportional to the rate of change of its momentum. For a body of MASS ‘m’, whose VELOCITY changes from u to v in TIME t, when force ‘F’ is applied. F∝TimeChangeinmomentum F∝tmv−mu F∝m(tv−u) ⇒F∝ma⇒F=kma(∵a=tv−u) ⇒F=ma(∵k=constant=1) Explanation: hope you understand it |
