state law of conservation of momentum and its applications
pls give me the answer
Answers
Answer:
The law of conservation of momentum states that the sum of momenta of the two objects before collision is equal to the sum of momenta after the collision provided there is no external unbalanced force acting on them.
One of the applications of conservation of momentum is the launching of rockets. The rocket fuel burns are pushed the exhaust gases downwards, and due to this, the rocket gets pushed upwards.
The principle of conservation of momentum states that if two objects collide, then the total momentum before and after the collision will be the same if there is no external force acting on the colliding objects.
Newtonian fluids are the best example: ideal gas i.e. air (at high temperature and low pressure) is the best application for law of conservation of momentum. Gas molecules contain energy absorbed from the surrounding and comes into motion.
