ATSC 110 Lecture Notes - Lecture 2: Kinetic Energy, Radiant Energy, Potential Energy
Document Summary
Chapter 2 energy: warming the earth and the atmosphere: energy, the ability or capacity to do work on some form of matter. Atsc 110: work is done when matter is either, pushed, pulled, lifted over some distance, doi(cid:374)g (cid:449)ork o(cid:374) so(cid:373)ethi(cid:374)g gi(cid:448)es it (cid:858)e(cid:374)ergy(cid:859) (cid:449)hi(cid:272)h it (cid:272)a(cid:374) use to do work on other things. Potential energy (pe: =(cid:1865) , m= mass, g= gravity, h= height above ground, potential energy is the stored energy in a mass that has the potential to do work. Kinetic energy (ke: =(cid:2869)(cid:2870)(cid:1865)(cid:2870, m= mass, v= velocity. If same speed, the object with greatest mass would have more kinetic energy. Forms of kinetic energy: heat energy, molecular motion, radiant energy, that received from the sun. First law of thermodynamics: law of conservation of energy, the total amount of energy in the universe remains constant, energy cannot be created, nor can it be destroyed. Specific heat of various substances (high low)
