The Momentum Dimension-Hi my friends!! This time, Suhu Pendidikan.com will share information with all of you, which is about the dimension of momentum which also includes Understanding,unit,formula,complete dimensions and examples

This time we will explain briefly, let's look at the following explanation: :

Definition of Momentum Dimension

What is meant by momentum dimension? which is a physical term that refers to the quantity of motion and mass in an object.

So that the definition of momentum can be interpreted as a magnitude obtained from the result of multiplication of a scalar mass of an object at a vector magnitude of its speed of motion..

So that momentum can be classified as a vector quantity ( is a magnitude that can be influenced by direction).

Which in the direction of the momentum matches the direction of velocity.

So that makes the momentum of a particle can be seen as a dimension that is very difficult to stop objects.

When the mementum swells, until it will continue to be terrible as well as the strength found in an item.

So that if the module is idle,, until the momentum will be equal to zero.

The same is true of the reverse when it continues to be fast moving, so that the momentum will continue to be great.

Then on the momentum that is on an object that is moving.

Formula for Momentum Dimension

After that in the designation used classical mechanics, which is momentum( can be represented by the letter P) so that it can be interpreted as a product of mass and velocity, until a vector is generated.

After that Momentum on an item or with a symbol( P) by having a mass denoted by the letter meter and moving with speed v so that it can be interpreted as follows::

p= meter. v

p= momentum( Kilogram meter/ s)

meter = mass of goods( Kilogram)

v= object speed( meter/ s)

Based on the formula above, so that we can describe the size of the momentum. follow the following method of parsing the dimensions:

[Momentum]=[pulp] x[speed]

=[M] x[L][T]- 1

=[M][L][T]- 1

until, The result obtained from the momentum measure is[M][L][T]- 1

Tree Size

What is meant by principal size? In physics that is a mass, long, time, electric current, temperature, seriousness of light and amount of substance.

After that, the other quantities that are still adrift are, for example, a kind of energy, then the acceleration which from so on can be described by a mixture of these quantities, Therefore, it is also known as the term derived quantity.

After that make a method where you know where the quantity comes from so that it can be shown by the size of the quantity.

After that to use the size so that we will prevent ourselves as being used by mechanics and character modules only.

• The mass size is written as [M]
• Length is written as [L]
• The time measure is written as [T]

Follow the parentheses on the letters in this chapter to show if we are the same- the same as dealing with the size.

After that on the size of each other quantity will participate in one or more of the dimensions- principal dimensions.

Example, in measuring a volume of an item until we want to relate the result of times of 3 the length of the length so that the size of the volume can be determined[L]3.

After that still use the same method to measure speed which relates the length after it is broken down with time, so that the size of the speed can be determined, namely[L][T]- 1.

Follow the description of the following table which shows a measure that is universally used in mechanics.

Dimensions

Large[L]2

volume[L]3

Speed[L][T]- 1

Acceleration[L][T]- 2

Style[M][L][T]- 2

Energy[M][L]2[T]- 2

Power[M][L]2[T]- 3

Pressure[M][L]- 1[T]- 2

Momentum[M][L][T]- 1

In physics, dimensions have 2 The role is very meaningful in order to be able to check an equation and also to get an equation.

Example Problem Momentum Dimension

Question

1. On any object when dipped into a fluid is a( liquid substance) to the point of feeling an upward force of pressure is uttered with( style of Archimides).

In this pressure force is strongly influenced by the density of the fluid ρ, after that on the acceleration of gravity gram and make the volume of the object that is inserted V.

So determine the force equation of the pressure!

The solution

At the size of the available size, namely:

In FA Style[M][L][T]- 2

Then Mass typeρ=[M][L]- 3

After that, the acceleration due to gravity gram =[L][T]- 2

Volume V=[L]3

• Next on the question, The equation for the magnitude of the upward pressure force can be described as follows::

FA=ρx gy Vz

After that to identify the value of x, y and z can be determined by analyzing from the equation on the measure found on the left and the right is?…

On Dimension- FA=ρxgyVz

[M][L][T]- 2=[M][L]- 3x[L][T]- 2Y[L]3With

=[M]x.[L]- 3x+ y+ 3z.[T]- 2Y

Therefore, the dimensions of both sides must be the same so that results can be obtained:

Squad[M]: x= 1

Squad[T]:- 2y =- 2 means y= 1

Squad[L]:- 3x+ y+ 3z= 1

– 3. 1+ 1+ 3z = 1 means z= 1

From the value of x, y and z can be obtained equation:

FA=ρ gram V

Thus and a short description that Suhu Pendidikan.com can convey about the dimension of momentum and hopefully it can be useful, thank you.
