Power is the time rate of change of energy, dE/dt= power= Force x velocity=Fv.
Power is the time derivative of Energy, P=dE/dt.
Power is measured in Watts.
The source of power.
Intensity = Power / Cross sectional area
Power is the rate of work done or rate of energy generated or expended
The physics definition of period is the duration of one complete cycle of a wave or oscillation.
In physics, velocity is the measurement of the rate and direction of change in the position of an object.
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

Physics is the science of motion and does not have anything to do with economics.
Physics
In physics, velocity is the measurement of the rate and direction of change in the position of an object.
All physics deals with energy and matter. In effect that is almost a complete definition of what Physics IS.
it is the branch of physics that deals with the structure and the behaviour of an atom is called atomic physics

The definition of engineering physics is an introductory college course in physics for potential engineering majors. This differs from regular physics in the inclusion of calculus in the curriculum instead of just algebra.
Since everything we encounter in the physical world is, by definition, physics, physics applies to everything--including elementary teachers.
In physics, energy is the capacity to do work.
