Some Facts about physics

Facts about Physics

Fundamentals Laws- The fundamental laws in physics are universal in nature, And it is applied in general and also can be applied in all subjects other than physics also without changing it

In physics we can study a wide range of topics from electron which is about 10^-14m. And have mass of 10³⁰ Kg to the biggest say Galaxy which 10²⁶m And have mass of 10⁵⁵Kg.

In Physics we can study about a wide range of forces

1. Gravitational Force which has strenghth of 10³⁰ and its range is infinite and it is applied all over universe.
2. Weak nuclear force which has a relative strength of 10¹³ and its range is about 10¹⁶m.
3. Electromagnetic force has an relative strength of 10^-2 and its range is infinite and it is applied in Electron and Neutron.And it happens on charged particles.
4. Strong nuclear force has a relative strength of about 10^-15m. This force is exerted by proton and neutron.
Note: Relative strength of any force is calculated with strong nuclear force.

Physical Quantity These physical quantities are conserved quantities and these does not change physical phenomenon and laws for these quantities are called laws of conservation.

Physics Laws do not change on time and become invariant.

Physics in Relation To Technology

In the field of technology non-resources are changed into sources by use of physics.

Many technologies are now in existence only due to the study of physics. Technologies use laws of physics and implement there and produce good technologies.

Important Devices and there Scientific Relation

The device Steam Engine is based on the principle of Thermodynamics.

The device Aeroplane is based on Bournaullis principle.

Laser light is based on the principle of Amplification by population inversion.

Hydroelectricity is based on the principle of Conversion of Gravitational energy into Electric Enery.
