Chapter 4: Energy •Sources:the sun, burning of fuel, electrical equipment. Light Energy •Object that moves fast has more kinetic energy than one moves slowly. •Heat energy make us feel warm and hot. •Light energy enable us to see. Potential Energy •A moving object has kinetic energy. Heat Energy Kinetic Energy Various form of energy •Energy stored in an object because of its position or condition •Sources:the sun, torch light, candle, lantern, lamp. •Sound that are produce from vibrating objects or when an object is hit. •Sources:musical instruments, alarm clocks. Electrical Energy Sound Energy •Sources: wind ,running, water, moving boat. •It is also known as electricity which is produce by the flow of electric current. •Sources:batteries, power stations. •There are 3 types of potential energy which are chemical potential energy, gravitational potential energy, electric potential energy. •Sources:spring, rubber band, food,chemical. Transformation of energy ENERGY Energy cannot be created or destroyed but it can be converted or transformed into other form motorcycle Chemical Energy Sound Energy + Heat Enrgy Kinectic Energy Light Energy Chemical Energy Chemical Energy Kinectic Energy + Sound Energy Chemical Energy Chemical Energy Electric Energy Energy Electrical Energy Chemical Energy Electric Energy Light Energy Light Energy + Heat Energy Heat Energy + Light Energy + Sound Sound Energy Electrical Energy Light Energy + Heat Energy Transformation of energy ENERGY Energy cannot be created or destroyed but it can be converted or transformed into other form. *examples of transformation of energy MOTORCYCLE LIGHT UP A CANDLE Chemical Energy Sound Energy + Heat Energy Kinetic Energy PLANTS MAKE ITS OWN FOOD Chemical Energy Light Energy + Heat Energy Computer Electrical energy Light energy Chemical Energy AEROPLANE Chemical Energy Sound Energy + Light Energy + Heat Energy RADIO Kinetic Energy + Sound Energy Electrical Energy SWITCH ON A TORCH LIGHT ELECTRIC CIRCUIT Chemical Energy Chemical Energy Electrical Energy Light Energy Sound Energy Electrical Energy Light Energy + Heat Energy
