2 FORMS OF ENERGY BACK HOMENEXT

3 TARGET AUDIENCE CLASS VI - VIII BACK HOMENEXT

4 LEARNING OBJECTIVES AFTER INTERACTING WITH THE SOFTWARE THE LEARNER WILL BE ABLE TO : 1. UNDERSTAND DIFFERENT FORMS OF ENERGY 2. DISTINGUISH BETWEEN VARIOUS FORMS OF ENERGY 3. UNDERSTAND TRANSFORMATION OF ENERGY BACK HOMENEXT

5 CAPACITY TO DO WORK IS CALLED ENERGY. MATTER POSSESES ENERGY AS A RESULT OF ITS MOTION OR POSITION IN RELATION TO THE FORCES ACTING ON IT. ENERGY BACK HOMENEXT

6 ENERGY ENERGY CAN EXIST IN VARIOUS FORMS :- 1.MUSCULAR ENERGY 2.MECHANICAL ENERGY 3.CHEMICAL ENERGY 4.LIGHT ENERGY 5.HEAT ENERGY 6.ELECTRICAL ENERGY 7.SOLAR ENERGY 8.SOUND ENERGY 9.NUCLEAR ENERGY BACKHOMENEXT

7 MUSCULAR ENERGY ENERGY STORED IN OUR MUSCLES IS CALLED MUSCULAR ENERGY. BACKHOMENEXT

8 MECHANICAL ENERGY BACK NEXT

9 MECHANICAL ENERGY KINETIC ENERGY POTENTIAL ENERGY IS THE ENERGY POSSESED DUE TO THE SHAPE OR POSITION OF THE BODY. POTENTIAL ENERGY BACK NEXT

10 MECHANICAL ENERGY KINETIC ENERGY IS THE ENERGY POSSESED DUE TO THE MOTION OF THE BODY. BACK NEXT

11 CHEMICAL ENERGY CHEMICAL ENERGY IS THE ENERGY THAT IS STORED IN CHEMICALS. CHEMICAL ENERGY CAN BE CONVERTED INTO ELECTRIC, LIGHT AND HEAT ENERGY. A voltaic cell harnesses the electrical energy of a chemical reaction to power a light bulb. BACKNEXT

12 LIGHT ENERGY Light is emitted from a source in straight lines and spreads out over a larger and larger area as it travels.Sources of light energy are bulbs,lamps etc. BACKNEXT

13 HEAT ENERGY HEAT IS ALSO A FORM OF ENERGY.EGGS ARE HATCHED DUE TO HEAT ENERGY.STEAM ENGINE USES ENERGY STORED IN THE FORM OF STEAM TO DO WORK. BACKNEXT

14 ELECTRICAL ENERGY BACK NEXT

15 ELECTRICAL ENERGY ELECTRIC CURRENT HAS THE CAPACITY TO DO WORK.THIS ENERGY IS CALLED ELECTRICAL ENERGY. ELECTRICAL BULBS, TUBES, MACHINES,ELECTRICAL ENGINES ETC. USE ELECTRICAL ENERGY. BACKNEXT

16 SOLAR ENERGY Flat plate collectors utilize the sun s energy to warm a carrier fluid, which in turn provides usable heat to a household "Solar Heating," Microsoft® Encarta® Encyclopedia © Microsoft Corporation. All rights reserved. Flat plate collectors utilize the suns energy to warm a carrier fluid, which in turn provides usable heat to a household solar energy contributes to the growth of plant life (biomass). SOLAR CELL, SOLAR COOKER ETC. USE SOLAR ENERGY. Solar Energy, radiant energy produced in the Sun as a result of nuclear fusion reactions. NEXT BACK

17 SOUND ENERGY SOUND IS ALSO A FORM OF ENERGY BECAUSE IT HAS CAPACITY TO DO WORK. SOUND OF CRACKERS AND HIGH FREQUENCY OF SOUND CAUSES CLUTTERING OF WINDOW PANES. BACKNEXT

18 NUCLEAR ENERGY Nuclear energy can be released in two different ways: by fission (splitting) of a heavy nucleus, or by fusion (combining) of two light nuclei. BACK NEXT

19 WIND ENERGY WIND ENERGY IS OBTAINED THROUGH WIND.WIND MILLS USE WIND ENERGY TO GENERATE POWER,TO DRAW WATER FROM THE WELLS OR TO RUN FLOUR MILLS. BACKNEXT

20 ASSIGNMENT 2.WHILE PLAYING WE USE ENERGY. 3.A MOVING BUS HAS ENERGY. 4A CELL USES ENERGY. 5. SPRING HAS ENERGY STORED IN THE FORM OF CAPACITY TO DO WORK IS CALLED BACK NEXT

21 AKNOWLEDGEMENT 2.MR. V. K. SODHI 3.MR. N. KAPOOR 1.ENCARTA ENCYCLOPEDIA 2000 BACK HOME
