Understanding Energy Transformations in Everyday Life

foreign ergy is all around us we can't see energy but we can see the things that energy does energy makes things move it Powers the machines we use it can make things get hotter or produce sound energy is used to light up our homes and cities and power the vehicles we use plants and other organisms need energy to live grow and Carry Out life processes energy cannot be created nor can it be destroyed but it can be changed or transformed from one form to another and we can observe this happening around us every day let's take a look at some examples as each video plays write down the energy transformations you think are taking place we'll go through each example at the end so you can check your answers let's go number one what energy transformation takes place when a ukulele is strummed number two what energy transformation takes place when a light bulb is switched on [Music] number three what transformation takes place when a match is struck number four what transformation takes place when a drawn bow and arrow is released number five what transformation takes place when an electric kettle is switched on number six what energy transformation takes place when a roller coaster rolls down the track number seven what transformation takes place when an electric doorbell is pressed number eight what energy transformation takes place when a drill is used to secure a screw into wood how'd you go let's take another look when a ukulele is strummed kinetic energy is transformed into Sound Energy when a light bar was switched on electrical energy is transformed into light and heat [Music] when a match is struck kinetic energy and chemical energy is transformed into light and heat when a drawn bow and arrow is released elastic potential energy is converted into kinetic energy when an electric kettle is switched on electrical energy is transformed into heat [Music] when a roller coaster rolls down the track gravitational potential energy is transformed into kinetic energy when an electric doorbell is pressed electrical energy is transformed into kinetic energy and sound when a drill is used to secure a screw into wood electrical energy is transformed into kinetic energy note that in many of the examples provided heat and sound are often produced [Music] don't forget to subscribe
