Question

State Newton second law of motion and law formula force.

Open in App
Solution

Dear Student,Newton's second law of motion states that the rate of change of momentum of an object is directly proportional to the unbalanced external force acting on it. The direction of the unbalanced force is the same as the direction of the change of momentum.Momemtum, P=mvLet the mass of an object be 'm' ,the initial velocity be 'u' and final velocity be 'v'.Initial momentum =mufinal momentum=mvRate of change of momentum =mv-mut=m(v-u)tWe know,acceleration ,a=(v-u)tRate of change of momentum=ma=F Thus, we can restate Newtons second law of motion as follows: Force acting on a body is equal to the product of its mass and acceleration.Regards.
