2 FORMS OF ENERGYS8P2. Students will be familiar with the forms and transformations of energy.c. Compare and contrast the different forms of energy (heat, light, electricity, mechanical motion, sound) and their characteristics.
3 What is energy? Energy is the ability to do work or cause change. Work is done when you transfer energy to an object and the object moves.
33 CONSERVATION OF ENERGY S8P2. Students will be familiar with the forms and transformations of energy.a. Explain energy transformation in terms of the Law of Conservation of Energy.b. Explain the relationship between potential and kinetic energy.
53 Where are KE and PE the greatest in this diagram?
54 How can energy be transferred? Energy can be transferred from one form to another.Turn on a lamp - - electrical energy transferred to light and thermal energy
55 Plants convert electromagnetic (light) energy from sunlight to chemical energy through photosynthesis.
56 Your body converts stored chemical energy from food into thermal energy and kinetic energy to make your body maintain body temperature and to move.
57 HEAT TRANSFERS8P2. Students will be familiar with the forms and transformations of energy.d. Describe how heat can be transferred through matter by the collisions of atoms (conduction) or through space (radiation). In a liquid or gas, currents will facilitate the transfer of heat (convection).
58 What is does temperature measure? The average kinetic energy of the particles in motion.
59 Same temperature – different thermal energy b/c more mass in big pot.
60 How is thermal energy transferred from one object to another? Heat
61 What is heat?Transfer of thermal energy from higher temperatures to lower.Can be transferred through matter in all three phases.
62 How can heat be transferred? ConductionConvectionRadiation
