Question

can anyone explain me second and third law of motion...?? And conservation of momentum..?? Its urgent.... tomorrow test..!!

Answer 1

second law states that rate of change of momentum is directly proportional to the force.As momentum increases,force increase

third law of motion states that action and reaction equal and opposite to each other.
e.g.a ball strike against a wall


law of conservation of momentum states that
the totalmomentum of the two objects before the collision is equal to the totalmomentum of the two objects after the collision.

Answer 2

example for third law of Newton hope you got your answer
