Teach High School Physics

Introduction to teach high school physics:
High school is the stage when the student is in tenth standard. When the student is in tenth standard, it is the first time when the student is giving the boards examination first time. Therefore, this stage is very important regarding the studies. Let us discuss that what are the important and marks scoring topics in the physics so that the student gain the very good marks.

Teaching of high school physics

Let us discuss the important topics of the physics at the high school standard which are marks scoring. The very first important and the interesting topic is optics. It is the branch of physics in which we deals about the reflection, refraction, dispersion of light. This is the geometrical optics, which we study in the high school. As we see our image in the mirror it is the example of reflection. As we see the coin inside the water it is the example of refraction. As the light passes from the prism it splits in the seven colors, it is the example of dispersion. Microscopes, telescopes, human eye and the defects of the vision also study in the high school physics. The second main topics are the electricity. In the electricity we deals with the current, resistance, ohm’s law, resistivity, temperature dependence of the resistance, series and the parallel combination of the resistances. The amount of the electric energy consumed, power loss are the topics, which are read in the high school physics. The main part of the electricity is electromagnetism and the electromagnetic induction, in which we study about the principle and working of the generator, we study about the Faraday’s law of electromagnetic induction, Lenz’s law, right hand rule, left hand rule and the screw rule. After that, we have to study about the sources of energy and the universe and solar system. These last topics are very easy as compared to the early ones. Having problem with The Shorter the Wavelength of Visible Light the keep reading my upcoming posts, i will try to help you.

Conclusion for teaching high school physics

Here from the above discussion we can conclude that the topics, which are read in the high school, are the base of the intermediate standard. So it is advised to study the high school physics with the great interest and in detail so there is no difficulty in the further studies.

Introduction to Physics in Daily life

Physics is  a science based on experimental, observative and quantitative measurement. It is the study of nature and the laws governing the nature and how energy and matter are related to each other.

Physics in Daily Life Examples

Physics forms an inevitable part of all branches of life. It has numerous applications in all fields of life. If we consider our daily life, whatever we do can be directly or indirectly connected to one or the other principle of Physics. Our walking, our eating. our talking all involves Physics. Physics is the backbone of many daily life example like electricity, computer, wrist watch, Car, refrigerator and so on.Understanding Definition of Gravitational Potential Energy is always challenging for me but thanks to all math help websites to help me out.

some of the very few  examples from our daily life which illustrates the principles of Physics are

i. We walk, walk fast, run, jog, jump into a bus etc. All these or any type of motion is associated with Newton's law of motion.

ii. When we talk, our vocal cords vibrate producing sound.

iii. When we eat food, the chemical energy of the food is being converted into mechanical energy which we use to do different types of work.

iv. The electricity is our house is a gift of Physics. Hydroelectric project is the method in which water is used to generate electricity.  The mechanical energy of the water is converted into electrical energy using dynamo.

Physics in Daily Life, Examples Continued

v. refrigerator works on the principles of thermodynamics

vi. Pressure cookers, washing machines, music system, computers all work on the principle of Physics.

vii. Automobiles, trains, aircraft all work on the concepts of Physics.

viii. While you are reading this article the working of your eye is similar to the working of a camera which again belongs to Physics.

ix. Mobile phones working on microwaves also uses Physics to connect people from different parts of the world.

x. Writing using Pen, writing on whiteboard using marker all are the sole properties of Physics.

xi. Rain, snowfall, lightening, thunder, wind, sea breeze etc all owe their existence to the laws of Physics

As mentioned in the beginning, the above list is endless. Any phenomenon of our daily life you consider, we an surely bring Physics in it.
