Electric fan

If you look at a definition of 'physics', everything an electric fan is, simply is physics.

For example, the fan itself, including the magnets and coils, fan blades and the air it moves, are all matter.
Electricity and almost every molecule in the known universe contains energy (everything above 0 degrees Kelvin) and thus movement.

And so the fan, matter, is switched on allowing electrons and protons to flow, in turn making the fan blades move, and exert force on the air, creating more movement aka air flow and eventually the air particles' movement is lost to friction, or heat energy.

Gadgets

Physics  deals with everything that connects with electricity . 

So it means gadgets are part of physics .

It also gives amusement , information , communication etc. 

Car

All of us have been a passenger in some type of vehicle at one time or another, 

and this makes cars something that we all can relate to. Since some physics 

principles are abstract, using a car as a means to illustrate these principles 

makes them easier to understand. The following information provides a solid 

foundation for teaching about the physics of cars. 

Force and Motion 

Motion is something we don’t think about very often, yet 

every activity we undertake involves it. Motion can occur 

naturally, be human produced or machine induced. For 

example, walking across a street, driving in a car, or a 

leaf floating from a branch are all examples of motion.
