Question #283f8

Answer 1

Physics is the branch of science, that deals with matter, energy and their mutual relationships.

Explanation:

Well, there are two classifications of physics;

1)Classical Physics:
In this one, we learn about the big things,like everything which is happening around us, like electricity, sound, velocity and temperature, like everything which has velocity less than velocity of light(3e8)

On the flip side;

2)Modern physics:
In this one, we learn about some really interesting stuff, like matter and energy conversion, Einstein theory of relativity, E=mc2, like everything which is small and has velocity approximately near to velocity of light (3e8)

Hope this helps.. :)
