ENGR 100 Lecture Notes - Lecture 27: Chemical Energy, Skateboarding, Sound Energy
Document Summary
An energy conversion is a change from one form of energy form to another. Any form of energy can change into any other form of energy. Example: conversion between ke and pe as a skateboarder travels up and down the half-pipe, his energy changes back and forth between kinetic energy and potential energy. When a skateboarder reaches the top of the half-pipe, his potential energy is at a. He speeds down through the bottom of the half-pipe, the skateboarder"s kinetic maximum energy is at a maximum. Chemical energy is stored in the food you eat. You body uses this chemical energy to function. The chemical energy in food is also transferred to thermal energy your body uses to maintain its temperature. Plants, through the process of photosynthesis, change light energy into chemical energy. Energy conversions are needed for everything we do. Heating our homes, getting energy from a meal, and many other things use energy conversions.
