Step-by-Step Solution:
Step 1 of 3

Key - Black = Everything, ​Highlight​ = Important, ​Highlight​ = Key Terms 7 Ideas That Shook the Universe - [PHY 11030] - Week 8 (3/6) -Tues 3/6 - Conservation of Energy [Ch. 18] ● Called electricity because the electrons are the ones that move, the electron is lighter and can move faster -Conservation of Energy ● Energy cannot be created or destroyed. However it can be converted from one type to another type ● The law of conservation of energy is sometimes called the first law of thermodynamics -Question ● When a rock is on top of a cliff what happens to its potential energy due to position when it falls to the ground ● As the rock falls, the energy is converted into kinetic energy ● Energy = (1/2) mv^2 -What is the final form of all energy ● Random kinetic energy which is heat Chapter 19: Heat and Temperature ● Heat and temperature do not have the same definition ○ An object can be very hot, but have little heat ○ An object can be cold, and have a large quantity of heat -Temperature ● Temperature is a function of how fast the atoms in an object are vibrating ○ High temperature = fast moving atoms ○ Low temperature = slow moving atoms -Heat ● Heat is the total random kinetic energy produced by all the atoms in an object Ex. Match ● Reason that match hurts is that the fire has very fast moving atoms that pound into your finger ● Very low heat in a burning match -3 ways to measure temperature ● Expansion: ​Principle
