## What are the applications of conservation of momentum in our daily life?

Rockets and jet engines also work on the law of conservation of momentum. In these hot gases produced by burning of fuel rush out with large momentum, Due to this, these machines gain an equal and opposite momentum. This momentum enables the rockets and jet engines with very high velocities.

How do you solve for conservation of momentum?

Conservation of momentum

1. Work out the total momentum before the event (before the collision): p = m Ă— v.
2. Work out the total momentum after the event (after the collision):
3. Work out the total mass after the event (after the collision):
4. Work out the new velocity:

What is an example of momentum in physics?

A tennis ball that hits on the racket with a high velocity has a smaller momentum (because of its less mass). So even if the player hits a tennis ball with less force, it will go to a greater distance.

### What is a real world example of the conservation of angular momentum?

The classic example of this is a spinning ice skater or someone spinning in an office chair. By pulling in her arms, the skater decreases her moment of inertia (all her mass is closer to the middle), so her angular velocity has to increase in order to keep her angular momentum constant.

Which of these are example of conservation of linear momentum?

Notes: Some examples of conservation of linear momentum: Recoiling of a gun. Explosion of bomb. Fight of rockets and jet planes.

How do you find the momentum of two objects after a collision?

Since the two colliding objects travel together in the same direction after the collision, the total momentum is simply the total mass of the objects multiplied by their velocity.

#### What is momentum Class 9 Example?

-A truck full of goods has a large mass and so it must slow down before a stop light because it has the large momentum with the same velocity and so it is very difficult to stop. -A moving bullet has a large momentum since it has an extremely large velocity though it carries very small mass.

Can you describe a real world example of momentum *?

– A karate player break a pile of tiles or a slab of ice with a single blow of his hand. This is because a karate player strikes the pile of tiles or the slab of ice with his hand very very fast. In doing so, the large momentum of the fast moving hand is reduced to zero in a very, very short time.

What is conservation of linear momentum with examples?

Before launch, the total momentum of a rocket and its fuel is zero. During launch, the downward momentum of the expanding exhaust gases just equals in magnitude the upward momentum of the rising rocket, so that the total momentum of the system remains constantâ€”in this case, at zero value.

## What is conservation of energy give two examples?

Other Conservation of Energy Examples Water can produce electricity. When water falls from the sky, it converts potential energy to kinetic energy. This energy is then used to rotate the turbine of a generator to produce electricity. The potential energy of water in a dam can be turned into kinetic energy.
