What is the different between eddy current and induced current

Simple pendulum was first introduced by Italy scientist Galileo in 1583

Thermonic emission was introduced by j.j Thomson in 1897

Transformer was invented by William Stanley in 1885

The study of light is called optics

Mirror
Any surface that formed imaj by reflection is called mirror

What is brìtish thermal unit

Heat
Thermal energy which flow from hotter object to colder object is çallèd heat

Physics is a Greek word whìch mean nature

The study of physical quantities is called physics

The father of electricity is Benjamin Franklin
The father of chemistry is jabir ibne hayàn

Charge was discovered by Benjamin frankliñ

What is science
Science is the knowledge which is obtained from observation and experiment

Charging by friction
When two neutral bodies rub each other thermal energy is produced that thermal energy work as an ionization energy to eject electrons from that solid surface having low ionization energy and enter these electrons to a solid having high ionization energy thus one body lose electrons possesses positive charge and other one gain electrons possesses positive charge hence this ìs called charging by friction

The surface interaction between solid bodies is called friction
