Dear student,

Driving an automobile is a perfect example of real world physics. The engine must overcome the first law of motion by exerting sufficient force to the wheels to make the car move. Without this force being applied, the car would stay at rest. This force causes a change in velocity (2nd law of motion). The 3rd law is exemplified by the road pushing the wheels in equal proportion to the wheels pushing the road.Right from driving an automobile, we enjoy physics.

Physics and technology benefit our daily lives in every aspect. Without the laws of physics, the world would be up-side down. And without technology, we would still be cavemen without the wheel.

As physics is all application oriented and robotic,we are less active and less socially involved.

Probably, this is the utmost disadvantage one can say about physics.

Hope this helps.
