a) Unification: It is the act of unifying the different laws valid for different phenomena in to a single theory that explains all the different phenomena. Eg. Electricity, magnetism and light are different phenomena and have different laws of physics for each of them.
b) Reductionism: A related effort is to derive the properties of a bigger, more complex, system from the properties and interactions of its constituent simpler parts. This approach is called reductionism and is at the heart of physics. Science is not based on assumptions while it is based on experiments.
c) Frame of Reference: A coordinate system with time frame is called frame of reference. Objects changing positions with time with respect to the frame of reference are in motion while those which do not change position are at rest. For a moving car, for the frame of reference outside the car, it appears moving.
d) Relative error: Relative error- when used as a measure of precision—is the ratio of the absolute error of a measurement to the measurement being taken. In other words, this type of error is relative to the size of the item being measured. RE is expressed as a percentage and has no units.
e) Instrumental error: Instrument error refers to the error of a measuring instrument, or the difference between the actual value and the value indicated by the instrument. There can be errors of various types, and the overall error is the sum of the individual errors. Types of errors include. systematic errors. random errors.
