Major Inventions in Physics Part-I

MECHANICS AND THERMODYNAMICS Mecahnic is concerned with the motion of particles or bodies under the action of forces and torque. Thermodynamics is concerned with the internal macroscopic state of the body. 1. Steam Engine (1712):   -A type of heat engine which uses thermal energy produced by steam in producing a mechanical work. -It's concept was proposed by ancient Greeks but practically it was Invented by Thomas Newcomen  in 1712. -In the late 18th century, to increase its efficiency and power,James Watt (Scottish engineer) made significant changes in the steam engine. -It boosted the industrial revolution as it aided in the mass production and the transformation of goods that is their transportation which facilitated the global trade thereby increasing the economic growth. -It has four parts which holds it principle of working:- •Boiler: Steam is produced as water boils by the heat in boiler. •Cylinder:A piston pushes down as steam is dir...

Wonders of Physics

Classical Physics Wonders Gravity: It is the force by which any body or planet draws object towards its center. It is this force that keeps us on ground and work as an aid for planets to be in their orbits around sun. Sir Isaac Newton discovered Gravity when he saw a falling apple while thinking about forces of nature.He determined each and every object has Gravitational Force in it. Gravity has many important functions like : - On earth Gravity gives weight to physical objects. -It helps to guide the growth of plants. -It influence the fluid circulation in organisms. - Moon's gravity is responsible for sublunar tides in the oceans. Electromagnetism : It is the force by which electrically charged particles interact with each other in the presence of a magnetic field. The field can be static,slowly,changing or in the form of a wave,these waves are transverse in nature. Hans Christian Oersted ,a Danish Scientist discovered electromagnetism in 1820. He, through his exper...
