Example Energy Conversion Paragraph
This paragraph is an example that students may use to help them with their Energy Conversion Paragraph homework assignment.
When I ride my bicycle, there are many energy conversions that take place, including chemical energy being converted into mechanical energy, mechanical energy being transferred into mechanical energy in different places, and mechanical energy being converted into kinetic energy. Chemical energy is converted into mechanical energy in my legs when my muscles contract and I push on the pedals. When I push down on the pedals, the mechanical energy from my legs gets transferred to the mechanical energy in the gears and the chain as they turn. The mechanical energy in the gears gets converted into kinetic energy of the bicycle as it moves. Throughout this process, there are several energy conversions and each time that happens some of the energy gets converted into heat due to friction of the chain on the gears and the tires on the road.
