PHYSICS IS EVERYWHERE

PHYSICS

Physics is a branch of science that deals with the study of matter and energy.Physics also makes significant contributions through advances in new technologies that arise from theoretical breakthroughs.

OBJECTS THAT SHOW PRINCIPLES,LAWS,AND THEORIES OF PHYSICS:

TELEPHONE

Alexander Graham Bell is generally acknowledged as the inventor of the telephone. Bell and others discovered that the sounds of speech could be converted to an electrical signal, 

transmitted over copper wires and converted back to sound at the receiving device.

This device has connection in physics. This matter exists energy. The branches of physics that telephones have are:

•   ACOUSTICS -  the interdisciplinary science that deals with the study of all mechanical waves in gases, liquids, and solids including vibration, sound, ultrasound and infra-sound. 
• ELECTRICITY AND MAGNETISM - the branch of physics concerned with magnetism produced by electric currents and with the interaction of electric and magnetic fields 

LAWS AND PRINCIPLES:

• PRINCIPLE OF WAVES AND SOUNDS

Wave motion transfers energy from one point to another, often with no permanent displacement of the particles of the medium—that is, with little or no associated mass transport.

TELEVISION

It is an electronic transmission of moving images with accompanying sound,sent - usually in color- from a central source or sources to home television screens.

It also have a physical science. The branches of physics that exists to it are:

•  OPTICS - the branch of science concerned with vision and the generation, nature, propagation, and behaviour of electromagnetic light. 
• ACOUSTICS - The science of sound, which in its most general form endeavors to describe and interpret the phenomena associated with motional disturbances from equilibrium of elastic media.
• THERMODYNAMICS - branch of science concerned with the nature of heat and its conversion to mechanical, electric, and chemical energy .
• ELECTRICITY AND MAGNETISM - Branch of physics that deals with the relationship between electricity and magnetism.
   

  LAWS AND PRINCIPLES:

•  First law of thermodynamics: Heat and work are forms of energy transfer. While energy is invariably conserved, the internal energy of a closed system changes as heat and work are transferred in or out of it. Equivalently, perpetual motion machines of the first kind are impossible.
• The principles of waves and sound 
• The principles of electricity, magnetism, and electromagnetism 
• The principles, sources, and properties of light.

               CELLPHONE

is a device that can make and receive telephone calls over a radio link whilst moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile phone operator, allowing access to the public telephone network.

It also have a connection to physics.
The branches it contains are:

•  OPTICS - Science concerned with the production and propagation of light, the changes it undergoes and produces, and closely related phenomena.
• ACOUSTICS -  the science of sound , including its production, propagation, and effects.
• THERMODYNAMICS - concerned with the nature of heat and its conversion to mechanical, electric, and chemical energy.

LAWS AND PRINCIPLES:

• First law of thermodynamics: Heat and work are forms of energy transfer. While energy is invariably conserved, the internal energy of a closed system changes as heat and work are transferred in or out of it. Equivalently, perpetual motion machines of the first kind are impossible.
• The principles of waves and sound 
• The principles of electricity, magnetism, and electromagnetism 
• The principles, sources, and properties of light.
