# Quick Answer: What Does Momentum Mean In Physics?

Momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Conversely, the momentum of a particle is a measure of the time required for a constant force to bring it to rest.

## How do you explain momentum?

Momentum can be defined as “mass in motion.” All objects have mass; so if an object is moving, then it has momentum – it has its mass in motion. The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving.

## How do you explain momentum to a child?

Momentum Facts. Momentum is a term that describes the strength of a moving object. Objects that are not moving, do not have any momentum. Things that are moving have less momentum if they are lightweight or moving slowly and the opposite is true if they are moving fast or are heavy.

## What is momentum in one word answer?

Momentum is defined as the amount of motion occurring in something that is moving, or the force that drives something forward to keep it moving. An example of momentum is how quickly a car is moving down a hill. (physics) (of a body in motion) The product of its mass and velocity.

## What is momentum in physics for kids?

Momentum is a measurement of mass in motion. Any object that is moving has momentum. In physics, momentum of an object is equal to the mass times the velocity. momentum = mass * velocity.

## What is momentum example?

So momentum equals mass times velocity or p = m x v. Therefore, if any object of any mass is not moving, its momentum is zero because its velocity is zero. Examples of Momentum: A 1000 kg car moving at 15 m/sec has a momentum of 15,000 kg•m/sec as a result of multiplying the mass and the velocity.

## What is called momentum?

Momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton’s second law of motion states that the time rate of change of momentum is equal to the force acting on the particle. See Newton’s laws of motion.

## What is momentum in real life?

Momentum in a simple way is a quantity of motion. If an object does not move then it has no momentum. However, in everyday life it has an importance but many people didn’t recognize it. Momentum is just about every activity that involves motion. It is an essential concept of physics.

## What happens when two objects collide?

In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum).

## What happens to momentum in a collision?

Momentum is of interest during collisions between objects. When two objects collide the total momentum before the collision is equal to the total momentum after the collision (in the absence of external forces). This is the law of conservation of momentum. It is true for all collisions.

## What’s the difference between mass and momentum?

We can define mass as the inherent property of matter. It is measured by mass×velocity, as momentum depends upon velocity, and it depends on the direction of the motion of the body as well. Momentum is a vector quantity since velocity is vector while mass is scalar.

## Why is momentum important in physics?

Momentum is important in Physics because it describes the relationship between speed, mass and direction. It also describes the force needed to stop objects and to keep them in motion. It can also predict the speed and direction of motion of objects after collision.

## Why is momentum conserved?

Impulses of the colliding bodies are nothing but changes in momentum of colliding bodies. Hence changes in momentum are always equal and opposite for colliding bodies. If the momentum of one body increases then the momentum of the other must decrease by the same magnitude. Therefore the momentum is always conserved.
