## What is momentum and its units?

Momentum. If the mass of an object is m and it has a velocity v, then the momentum of the object is defined to be its mass multiplied by its velocity. momentum= mv. Momentum has both magnitude and direction and thus is a vector quantity. The units of momentum are kg m s−1 or newton seconds, N s.

### What is the basic unit for momentum?

In symbols, linear momentum p is defined to be p = mv, where m is the mass of the system and v is its velocity. The SI unit for momentum is kg · m/s. Newton’s second law of motion in terms of momentum states that the net external force equals the change in momentum of a system divided by the time over which it changes.

Is N MA unit of momentum?

One newton-second corresponds to a one-newton force applied for one second. It can be used to identify the resultant velocity of a mass if a force accelerates the mass for a specific time interval….

Newton-second
Unit of Impulse and momentum
Symbol N⋅s or N s
Named after Isaac Newton
In SI base units: kg⋅m/s

How do you calculate momentum?

The Momentum Calculator uses the formula p=mv, or momentum (p) is equal to mass (m) times velocity (v).

## What is the dimensional formula of momentum?

Dimensional Formula:

Permeability of free space (μo=4πFd2m1m2) Hm –1 or NA –2 MLT –2I –2
Permittivity of free space (εo=Q1Q24πFd2) Fm –1 or C 2N –1m –2 M –1L –3T 4I 2
Planck’s constant (energy/frequency) Js ML 2T –1

### What unit is kg/m s?

The kilogram-meter per second (kg · m/s or kg · m · s -1 ) is the standard unit of momentum . Reduced to base units in the International System of Units ( SI ), a kilogram-meter per second is the equivalent of a newton-second (N · s), which is the SI unit of impulse .

What is the formula for final momentum?

What is dimensional formula?

Dimensional formula (equation) (Definition) : An equation, which gives the relation between fundamental units and derived units in terms of dimensions is called dimensional formula (equation). In mechanics the length, mass and time are taken as three base dimensions and are represented by letters L, M, T respectively.
