Why Do Living Things Need Energy? All living things need energy to survive. Nearly all the energy for life comes from the sun. Autotrophs are organisms that make their own food. There are two laws of Thermodynamics: • First Law- The law of conservation of energy‚ which states that energy can be converted from one form to another‚ but it CANNOT be created or destroyed. • Second Law- States that energy cannot be converted without the loss of usable energy IMPORTANT TERMS Energy- the ability

Energy Conservation Jessica Goode Axia College of University of Phoenix We all use energy each and every day. We use energy for entertainment‚ cooking‚ transportation‚ lighting‚ heating‚ cooling‚ manufacturing‚ as well as many other things. According to the Webster Dictionary (2009)‚ energy is defined as just being active. If that is truly the case‚ then anytime we are doing anything we are being active and using up energy. Shouldn’t we try to conserve more energy if that is the case? According

the law of conservation of energy? What are the dampening properties of a real mass-spring system that vibrates vertically? Hypothesis If a real vibrating spring suspended vertically undergoes damped harmonic motion‚ then it will support the law of conservation of energy because the energy at all points of the motion is equal. Even though the total amount of mechanical energy decreases over time‚ the other energy is not lost‚ but instead becomes thermal energy. This thermal energy is produced
