 Physics ;-

"The branch of science which deal with the study of properties of Matter,Energy and their Mutual relationship."

 OR ;

"the study of Nature is called science"

 Explanation; 

In the above first definition we study about various kinds of Matter as well as we study Energy and mutual relationship means interference between them.

 Example ;

if we switch on the current start flow in a wire and goes toward materials (Fan,Light,etc) and then the Fan start moving,so here is a point the Fan is Matter and the current which moving in a wire is Energy this is the Mutual Relationship between Energy and Matter.

and the study of these things is known as Physics.
