  2. Contents PHYSICS GEOMETRY

  3. PHYSICS SCIENTISTS MAIN TERMS IT WAS INTERESTING TO KNOW BACK

  4. SCIENTISTS LORD KELVIN ALBERT EINSTINE BACK

  5. MAIN TERMS Motion Waves Energy BACK


  6. IT WAS INTERESTING TO KNOW BIG BANG LASERS RADIATION BACK

  7. GEOMETRY SCIENTISTS MAIN TERM IT WAS INTERESTING TO KNOW BACK

  8. SCIENTISTS EUCLID Archimedes BACK

  9. MAIN TERM SOLID FIGURES BACK

  10. IT WAS INTERESTING TO KNOW Graphs Statistics Trigonometry BACK

  11. GRAPHS • We can see the relationship between two or more pieces of information by using graphs and can present numerical data as a picture. This allows more simply to understand and use the data. BACK NEXT

  12. GRAPHS The simple graphs: • Vertical axis (Y-axis) • Horizontal axis (X-axis). The point where the axis meet is known as zero point. BACK

  13. Statistics • Statistics is the branch of mathematics concerned with collecting and interpreting data. The data are often collected by interviewing a sample group of people. BACK NEXT

  14. Solidfigures • The solid figures most easily categorized are called polyheadra. • Five regular polyheadras: • Tetrahedron (four triangular faces) • Octahedron (eight triangular faces) • Dodecahedron (12 five-sided faces) • Rosaheadron (12 triangular faces) • The cube (six square faces) BACK

  15. Euclid • Worked in Alexandria, Egypt, 2300 years ago; • He is a famous for writing Elements, a series of 13 books; • Wrote on music and other subjects. BACK

  16. Statistics • The information going from the sample group of people can be useful in government agencies and businesses. BACK

  17. Trigonometry • Trigonometry is the branch of mathematics connected with the relationship between sides and angles of triangles. • Trigonometry can be used to find the measurements of unknown sides and angels of triangles. BACK

  18. Motion Everything in the world is in motion. Examples of motion: • Objects (rocks and buildings) • Flight of an airplane and etc. BACK NEXT

  19. MOTION The Earth itself is moving around the sun. All motion requires force to start, to change speed or direction, or stop. BACK

  20. WAVES Some waves transport energy through matter by causing the matter to vibrate. Types of waves: • Transverse (crosswise) waves • Longitudinal (lengthwise) waves BACK

  21. ENERGY Everything happens because of energy. Types of energy: • Chemical energy • Light energy • Nuclear energy BACK NEXT

  22. ENERGY Energy can switch one form to another when work is done. BACK

  23. Albert Einstein • Introduced new theories about the nature of time, space, energy, and gravity. • His theories were used to produce nuclear bombs. BACK

  24. Lasers • «Light Amplification by stimulated Emission of Radiation» • A devise for converting ordinary light into an intense narrow bean. • Passes an electric current through material: solid, liquid, gas. BACK

  25. Radiation Alpha rays Beta rays Gamma rays 2 protons 2 neutrons + charge No mass No charge Electrons - charge BACK

  26. Lord Kelvin The founder of modern British physics. His name is given to a unit of temperature. Calculated that the lowest t any matter could achieve -273C. BACK

  27. The Big Bang. • Some scientists believe that the universe was born 15billion years ago in a colossal explosion called the Big Bang. • The young universe began to expand rapidly and tiny particles of matter formed. • Over millions of years this matters began to develop into the first galaxies. BACK

  28. Archimedes • discovered the value of “pi”, which is the ratio of the circumference of a circle to its diameter; • looked for ways of measuring the volume and mass of irregular objects; • discovered the principle of displacement. BACK
