A micro-mirror projector uses millions of microscopic mirrors to form the images that we see on the screen. This technology still uses a very bright lamp, in this case to shine light through a prism that splits it up into color beams. How does a projector work optics? Two converging lenses refract the light so […]
For physicists, math is a tool used to answer questions. For example, Newton invented calculus to help describe motion. For mathematicians, physics can be a source of inspiration, with theoretical concepts such as general relativity and quantum theory providing an impetus for mathematicians to develop new tools. What topics of maths are used in physics? […]
The SI unit of force is the newton, symbol N. What is SI units PDF? SI units comprise a coherent system of units of measurement starting with seven base units, which are the second (the unit of time with the symbol s), meter (length, m), kilogram (mass, kg), ampere (electric current, A), kelvin (thermodynamic temperature, […]
Relative density. = mass of certain volume of substance (or material) / mass of an. equal volume of water. Note that for any substance/material. What is relative density in physics? Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given […]
Initial velocity describes how fast an object travels when gravity first applies force on the object. On the other hand, the final velocity is a vector quantity that measures the speed and direction of a moving body after it has reached its maximum acceleration. What are the 5 kinematic formulas? v = v 0 + […]
Gravity is one of the four fundamental forces in the universe as well as the most vulnerable of the four basic forces. Gravity seems to be a repressive force. Gravity has the ability to function over large distances. Gravity could not be characterized as a force of interaction or attraction. What is gravity physics? Gravity […]
In statistical mechanics, we consider microscopic interactions and do the math based on apriori assumptions(postulates). Thermodynamics deals with averages. It is a science of time-scales and length-scales. What is statistical thermodynamics in physics? Statistical thermodynamics is a theory that uses molecular properties to predict the behavior of macroscopic quantities of compounds. What is the relation […]
Concept mapping is a meta-learning strategy based on the Ausubel-Novak-Gowin theory of meaningful learning. In a concept map, concepts are related with linking words to form propositions. By expanding this concept-proposition link, one eventually forms a web of concepts whose meanings are embedded in the presented map. How do you write a concept map in […]
Aristotle’s Law of Motion: The natural state for an object is to be at rest. If you don’t push on an object, it will stop moving. What is Aristotle known for in physics? In his work Physics, Aristotle intended to establish general principles of change that govern all natural bodies, both living and inanimate, celestial […]
Course Description The areas of physics include motion, fluids, heat, sound, light, electricity and magnetism and modern physics (relativity and atomic structures). BCC is an International Baccalaureate School; and IB Physics 2 is structured to meet the goals of the IB diploma program. What is the best IB physics textbook? Tsokos’ “Physics for the IB […]
When atomic number changes, number of protons in the nucleus changes and so does the number of electrons. This completely changes the element as the properties of the atom will change. So, atomic number is unique for each element and therefore considered as “fingerprint” of elements. What is nuclear physics in simple terms? Nuclear physics […]
Radiation is classified into two main categories: non-ionizing and ionizing, depending on its ability to ionize matter.
