Question

State and derive the formula of Newton’s second law of motion.What is the law of conservation of momentum, explain with an example?

Answer 1

Newton's second law of motion states that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass. In equation form, Newton's second law of motion is a=Fnetm a = F net m .

Newton's cradle is an example of the Law of Conservation of Momentum. An example of law of conservation of momentum is Newton's cradle, a device where, when one ball is lifted and then let go, the ball on the other end of a row of balls will push upward. ...

${\underline{\sf{\green{Newton's\:Second\:Law\:of\:Motion}}}}$

Newton's second law of motion states that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass.

The object experiences an acceleration due to gravity (g) = m × g

${\underline{\sf{\green{Law\: of\: conservation \:of \:momentum}}}}$

In physics and chemistry, the law of conservation of momentum states that the momentum of an isolated system remains constant. Momentum is therefore said to be conserved over time; that is, momentum is neither created nor destroyed, only transformed or transferred from one form to another.
