# What will be the momentum of a body of mass m which is moving with a velocity v?

P = M × V.

## What is the quantity of motion of an object mass in motion or inertia in motion?

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.

## What is the motion of a moving object determined by the product of its mass and velocity?

In symbols, linear momentum is expressed as p = mv. Momentum is directly proportional to the object’s mass and also its velocity. Thus the greater an object’s mass or the greater its velocity, the greater its momentum. Momentum p is a vector having the same direction as the velocity v.

## How do an object’s velocity and mass affect the amount of momentum that it has?

Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.

## What is SI unit of momentum?

Momentum
SI unit kilogram meter per second (kg⋅m/s)
Common symbols p, p
Other units slug⋅ft/s
Dimension MLT1

## What is the momentum of a man of mass 75 kg?

The momentum of a man of mass 75 kg when he walks with a uniform velocity of 2m/s. We have to find momentum of that man. Thus, momentum of a man is 150 kg. m/s.

## Is inertia Newton’s first law?

Newton’s First Law: Inertia Newton’s first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This tendency to resist changes in a state of motion is inertia.

## What is Newton’s 2 law?

Newton’s second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.

## How to calculate inertia?

Generally, for uniform objects, the moment of inertia is calculated by taking the square of its distance from the axis of rotation (r2) and the product of its mass. Now, in the case of non-uniform objects, we can calculate the moment of inertia by taking the sum of individual point masses at each different radius.

## What is the formula for the mass of a moving object?

As the object approaches the speed of light, the object’s energy and momentum increase without bound. Tolman in 1912 further elaborated on this concept, and stated: the expression m0(1 − v2/c2)−1/2 is best suited for the mass of a moving body.

## What is the difference between speed and velocity?

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.

## Why does the movement of an object depends on the mass of an object?

The more mass an object has, the greater its inertia and the more force it takes to change its state of motion. The amount of inertia an object has depends on its mass – which is roughly the amount of material present in the object.

## What is the momentum of a body of mass 2m and velocity v 2?

Given: Mass of the body, m = 2m, Velocity of the body, v = v/2. Therefore, the momentum of the body is mv.

## What is momentum of a moving body equal to mass into?

Momentum (P) is equal to mass (M) times velocity (v). But there are other ways to think about momentum! Force (F) is equal to the change in momentum (ΔP) over the change in time (Δt).
