WHAT IS PHYSICS ?
Physics is a pure science that deals With the behavior of matter and energy and how it relates to other Physical  properties.
                A well study of the subject indicates that physics is a everyday science. It has an effect on whatever we do . Besides, certain principle in physics is sometimes apply yo achieve our goals. For instance, the clinical thermometer used in hospitals or in homes to determine temperature of a body;the filament bulb or Fluorescent tube for producing light effect;the electric or gas cooker used at homes;the camera for taking pictures e.t.c
                Scientists of many different nationalities are today doing research in physics. As a result, many useful inventions and machines  have been produced.
  Examples:-computer in banks;radar control at the airport ;colour television transmission ;high power microscopes for use in medical research ;and anti-skid tyres for cars.
               In order to have the fact about the fundamental concept, physics is divided into two main branches.
CLASSICAL PHYSICS:-E.g  mechanics, optics, heat, optics, wave, sound, electricity and magnetism.

MODERN PHYSICS :-It covers the aspect of matters, energy and their relation at atomic and subatomic levels, developed for the interest in the study of physics and  along with other subjects. Examples are Geophysics, Astrophysics, Biophysics and Engineering physics. 

       HOW TO BE A PHYSICS ENTHUSIAST
Physics can be studied by developing a behavior that encourages positive study habits. To understand the basic concepts in physics, one must be able to..
-Think clearly
-Observe exactly and truthfully
-Have a study plan
-Have a role model to look up to.

          WHO IS A PHYSICIST 👩‍🔬?
A physicist is a person who studies and understands the reason for the existence of natural things and why they occur, the way they do. Also, a scientist who has a special knowledge and training in physics.

        THEORY AND EXPERIMENT
Theory is a statement of idea, which  is only acceptable if there is an experimental prove to support it. Examples, the idea of ISAAC NEWTON provides a good understanding of motion and the effect of force.GRAPHING.  EINSTEIN discovered the law of photoelectric effect that gave the foundation of making photocells in burglar alarm. NEIL BOHR gave an insight into the structural radiation of an atom.
     Scientific experiment confirms thoreactical ideas. They also helps in examine the relationship between operating parameters. Examples, the relationship between volume of a gas and the corresponding temperature effect.



           GRAPHING
One of the most aspect of physics is GRAPHING. 
 A good graph shows clearly the relationship between the variable quantities under experimental observation.
       

        TYPES OF GRAPH
-Straight line graph.
-Parabola.
-inverse graph.

Gravity.

Which is the best explanation for the earth's gravity?.... If mass was responsible for the effects of gravity, this means that a more massive object's stronger attraction to the earth's mass, would fall faster then any less massive objects, when we know that this does not happen. Because all objects have to fall at the same rate of speed regardless of their mass... Where it is actually reverse gravity (centrifugal force) that neutralizes gravity's acceleration on an object, causing all objects to fall at the same rate of speed, regardless of their mass (which better conforms with experiments)...  Whenever we are in a fast traveling vehicle and it changes its direction of travel, we always experience a force. This is why we experience a force with centrifugal force because its rotation is "a constant change of direction", which creates a constant force (reverse gravity). Written: Alan Halonen.

Optics

Optics is simply put as the scientific study of sight and light. The ways employed in producing images are through the camera & projector and the human eye. The simple lens camera is made up of a convex lens(in complex cameras, this is replaced by a system of lenses), a diaphragm,  a shutter,  a film and a film spool. The projector is made up of the small but powerful light source that illuminates the non-luminous transparent object,  the condenser  which is made up of two plano convex lenses which collects the light to evenly illuminate the film,  the slide carrier which is the framework in which the slide is placed upside down, so that it will appear erect on the screen. The projection lens which is placed in front of the slide to give a magnified, real and inverted image of the slide, but, because of this, the slide is placed upside down so that the image formed on the screen is in an erect position. Lastly, the screen, usually white, receives the i...

Density

Physics-helper  Subject :- Density Hello guys Am Kolapo one of the admin @ Physics-helper And am sure at the end of this lesson you should be able to know more about Density The density of a substance is defined as the mass of the substance per unit volume Which can be expressed mathematically as :- D=M/V Where D= Density             M=Mass             V=Volume       Determination of Density Of A Solid 1) Regular shaped solid :-        The mass a regular shaped solid is obtained with the aid of a chemical balance. It's volume is calculated from the measurement made by using either the Vernier calipers or a micrometer screw guage depending on size and shape of the solid. The density can be obtained by using the formula D=m/v 2) Irregular shaped solid :-     The volume of an irregular shaped solid is found by displacement method Relative Den...
