Wikipedia gives you a good definition and a very large list of areas.
There's also the "Simple English" wikipedia.
They give a very short and good definition for Physics.
See http://simple.wikipedia.org/wiki/Physics
In physics, mass is the aggregate of matter in a body that is a measure of its inertia.
Please see the answer in the related links.
The same as in modern physics: there is really no physically meaningful way to define absolute motion.
In weight it is means it is not heavy. In physics it is electromagnetic radiation that can produce a visual sensation.

i donjt no
There are actually many areas on physics. I am not sure which specific areas you want to know about in physics. So, I guess I am unable to answer you question. Sorry.

Classical physics and (Quantum or modern) Physics Mechanics Thermodynamics Sound Light Optics Magnetism Electricity
Branch of Physics that applies to life science is called Biophysics .
In physics and astronomy, a star is a huge globe of plasma that emits its own radiation.
it is the study of math and and chemistry put together
it is a unit distance covered at a unit speed

Define Electrostatics
physics is divided in to two type.1-classical phy,2-modern phy. classical phy. in which the energy is continuous but modern physics in which the energy is discrete
