Momentum in Physics and its Application in Daily Life

Momentum in physics is found in objects that are in motion. Every object that moves must have a force of motion.

This is often referred to as momentum. The magnitude of the momentum will depend on the mass and velocity of the object. Generally a momentum always involves two or more objects.

Know the Definition of Momentum in Physics

Every object in motion generally has a momentum. Momentum refers to the quantity of motion and mass of an object.

Momentum is also a product of multiplication. Both the scalar quantity of an object’s mass and the vector quantity of its velocity of motion.

Launching Wikipedia, momentum is a quantity that has a relationship with the velocity and mass of the object.

Momentum is also a vector quantity which is affected by direction. The direction of the momentum is usually in the direction of the velocity.

The momentum of a particle is also seen as a measure of the difficulty of stopping the object. The greater the momentum, the greater the force on an object.

When matter is at rest, its momentum is zero. However, the faster the movement, the greater the momentum.

Application of the Law of Conservation of Momentum

The law of conservation of momentum describes two objects colliding. The magnitude of the decrease in momentum on one of the objects will have the same value. Of course with a large increase in momentum on other objects.

This means that the total momentum of the object system before the collision occurs is the same as the magnitude of the momentum of the other object systems.

Especially after the collision. The following is an explanation of the application of momentum in physics in everyday life.

Rocket Principle

The principle when propelling a rocket can fulfill the law of conservation of momentum. In the initial state of the rocket and fuel system at rest, so the momentum becomes zero.

After the gas appears to be leaving the rocket, the momentum of the system remains. So that the momentum of the system before and after the exit of the gas becomes the same.

According to the law of conservation of momentum, the final speed a rocket reaches depends on the amount of fuel in the rocket and the speed at which the gases are emitted. Basically, these two quantities are fairly limited.

So that its use is on staged rockets or multistage rockets, namely several combinations of rockets. When the first fuel condition has run out, the rocket will be released.

The spacecraft undergoes rapid movement with the total mass of the aircraft and rockets lighter. That’s because it no longer carries the first rocket.

In the second stage it can reach its final speed which is much faster. And so on until all the rockets have been burned.

Jet Engine Principle

As with rockets, the working principle of a jet engine also applies the law of conservation of momentum. But what distinguishes it is the oxygen fuel in the rocket is in the rocket tank.

While the jet engine by taking oxygen from the surrounding air. Rockets can generally work in space, while jet engines cannot. On the other hand, jet engines can only operate in the atmosphere.

Momentum in physics is generally present in every moving object. The greater the momentum, the greater the force on an object. (R10/HR-Online)
