what is meant by physical world?what is the use of physics in our daily life?give some examples of the things which we use in our daily life which are based on physics?

so you had started first chapter of class 11. it is not such a important chapter but just a introduction
phsical world tells role of physics in this world. physics play a great role in daily life. for example all the concepts including how we walk, how to play , preperation of medicine making of vehicles, making aeroplanes etc. can only be understood with physics help.
so donot be confuse . just give a simple reading to chapter
best of luck
thanks and approve
