# Measurements, Dimensions and Units

<<<  Previous Next >>>

Physical quantities are basically identified using any of the following basic classifications :

amount of substance, length, mass, time, electric current, thermodynamic temperature, luminous intensity

Length

Practically we cannot find a fixed point in space. Everything is motion for everything take part in the process of attraction and repulsion. In order to measure the distance between two locations  we should  fix a point with reference to another point in following manner : If there is known point in a straight rod, this primary unit should have a fixed number of molecules(n)  having closely fit ( ensured that it will not change its size) to each other having the diameter D, so that the primary measuring unit of meter should have a length denoted by  n.D .

We measure all other objects based on this primary unit.

Length between two points measured based on a primary object such as meter or foot.

Weight and Mass

Particles attract each other.

Weight is the attractive force towards earth.

Mass is the quantity how much dense it is. As we know,  it is   Volume x density . Density is a numerical value.

Let us assume the particle ultimatum that cannot divide any more and even light & heat also made up of ultimatums. Let us assume the volume of ultimatum is u and let a,b,c,d, e are indicating some numerical value. Also it is to be note that moving particles are avilable in the form of energy while static particles are treated as materials.

Then size of light particle = au; heat particle = bu; and electromagnetic particle = cu.

Similarly, any matter can be expressed in terms of how many times it is dense in terms of ultimata.

As we have stated earlier matter is a spot of energy. The most basic form of matter as we know, is hydrogen atom, available as hydrogen molecule. Let us assume this quantity as E, having a combination of energy quantities q1+q2+q3+......+qn

Our units for energy is joules having units M.(L/T)2. No matter in what form it is available if it is energy and could be able to express in joules. In this picture the quantity is  represented symbolically. So if we assume all energy quantities were measured in same units we have to identify these volumes in terms of particular block. So all the Energy available is:

1.q1+k2.q1+k3.q1+..............+kn.q1= K.q1;

where K= k1+k2+k3+.........+kn ,

q1 is the primary energy packet; k is the type of factor defining energy density.

........ .............. .....( involve further developments)

References:

Planck's constant:
The resulting law states that the energy of each quantum is equal to the frequency of the radiation multiplied by the universal constant: E=f*h, where h is 6.63 * 10E-34 Js.

Force of attraction :
The value of a physical quantity  is expressed as the product of a unit  and a numerical factor

### F  =k. Energy expressed in Joules  =M L.L/t.t
W = FD.      Work = Force x distance

Work is equivalent to kinetic energy KE = ½mv².

W = Fd.      Work = Force x distance
F = mf.          Force = mass x acceleration
1 Wh = 3.6 x 10 3 J .

The definition of work is that it equals force times the distance traveled while that force is being applied or W=FS
where: W is the work in joules (J or kg-m²/s²), F is the force applied to an object in Newton's (N or kg-m/s²), s is the distance the object moves.

### Mathematics

The expression x²+1=0 means something multiplied by the same number of time the quantity, added to 1 will be equal to zero. This cannot be possible in any case.This means it's a false statement.

If x is considered as imaginary number we assume i² = -1

where i = Square root of -1. This way we define imaginary numbers with a false statement from the begining.
