Introduction to physics--Branches of Physics--Importance of physics

This presentation covers about physics, branches of physics and importance of physics in a very interactive manner. I hope this presentation will be helpful for teachers as well as students.

1. INTRODUCTION TO PHYSICS

2. Sunrise in the morning Sunset in the evening

3. Heat & light from burning Yellow orange colour of sky

4. Falling of objects Birds flying in the sky

5. Formation of ocean waves Sinking of objects

6. Spherical shape of soap bubbles Moon orbiting around the earth

7. In order to play cricket, football, chess, hockey or any other game we follow some rules Similarly, the physical phenomena of our nature follow some rules or principles

8. DISCOVER BASIC LAWS NATURE PHYSICAL PHENOMENA OBSERVATION Falling of an apple from a tree Orbiting of the moon around the earth Newton Observed Laws of motion Law of Gravitation

9. Physics is the study of various physical phenomena and the fundamental laws governing them . PHYSICS NOTE: The laws of physics are not invented by people, they are only discovered

10. P hysics is a natural science (Deals with natural phenomena) P hysics is a physical science (Deals with our physical world) P hysics is a fundamental science (Deals with most basic things of nature)

11. Force Motion Heat Sound Matter Electricity Magnetis m light MOST BASIC THINGS OF NATURE

12. Natural Phenomena Physical Chemical Biological Formation of rainbow Formation of clouds Conversion of wood into ash Rusting of iron Pumping of blood by heart Exchange of gases through lungs

13. BRANCHES OF PHYSICS

14. PHYSICS Classical Physics Modern Physics Developed before 19 th century Developed after 19 th century Classical mechanics Atomic physics Wave physics Thermodynamics Electromagnetism Optics Nuclear physics Quantum mechanics

15. CLASSICAL MECHANICS Classical mechanics is the study of effects produced by a force. Motion of a car Loading on a bridge Working of hydraulic machines

16. WAVE PHYSICS Wave physics is the study of effects produced by a vibration or an oscillation. Sound produced by a violin To and fro motion of swing Waves on water surface

17. THERMODYNAMICS Thermodynamics is the study of effects produced by a heat. Expansion of mercury in a thermometer Working of an engine Working of a refrigerator

18. ELECTROMAGNETISM Electromagnetism is the study of effects produced by an electric charge or a magnet. Working of a speaker Generation of electricity Working of an UPS inverter

19. OPTICS Optics is the study of effects produced by light. Image produced by a plane mirror Colour of the sky Eyesight correction using spectacles

20. ATOMIC PHYSICS Atomic physics is the study of the structure of an atom and c haracteristics of subatomic particles. Working of a LASER Neon sign board Working of X-Ray Machine

21. NUCLEAR PHYSICS Nuclear physics is the study of an atomic nuclei and their constituent particles. Carbon dating Working of Radiotherapy Machine Nuclear power generation

22. QUANTUM MECHANICS Quantum mechanics deals with the behavior of matter and energy at atomic scale. Magnetic Resonance Imaging S mart phones Electron microscope

23. IMPORTANCE OF PHYSICS

24. Without knowledge of fundamental principles of physics Biologists cannot understand H ow brain controls our body? H ow plants carryout photosynthesis?

25. Without knowledge of fundamental principles of physics Chemists cannot understand Why firework produce different colours ? H ow G oldplating works?

26. Without knowledge of fundamental principles of physics Geologists cannot understand Formation and eruption o f lava Why earthquake occurs?

27. Without knowledge of fundamental principles of physics A stronomers cannot understand How planets revolve around the sun? Why stars shine in night sky?

28. PHYSICS The Foundation Of Science

29. Without knowledge of fundamental principles of physics Civil Engineers cannot design buildings, bridges, dams, overhead water tanks etc.

30. Without knowledge of fundamental principles of physics Mechanical Engineers cannot design automobiles, space vehicles, wind turbines, machines etc.

31. Without knowledge of fundamental principles of physics Electrical Engineers cannot design power substations, transformers, motors, electrical panels etc.

32. Without knowledge of fundamental principles of physics Electronic Engineers cannot design circuits, antenna, radar system, robotic arm etc.

33. PHYSICS The Foundation Of Engineering
