2.13: Write a short note on A) Newton's second law of motion B) Law of Conservation of momentum.
Answers
Explanation:
A) Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object...
B) The law of conservation of momentum states that the total 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...
Answer:
2nd law: the rate of change of momentum of an object is directly proportional to the unbalanced force that acts on it
law of conservation of momentum: the momentum of two objects remains same even after their collission
