Forms of Energy

energy is

what is needed to do work or cause change.

energy is produced by the movement of electrons

electrical

what does g stand for in E_p=m x g x h

gravity is 9.8 on earth

potential energy + kinetic energy

mechanical

Energy that causes a transfer of heat between materials

thermal

if we say energy is lost what do we really mean

Energy can do things humans don't want

electromagnetic energy

light

energy produced from air vibrations. It travels in waves that we can hear due to vibrations of matter

acoustic

anytime anything moves energy is involved(true or false)

true

what type of energy powers a computer when its not plugged in

chemical to electrical

a lamp uses electrical energy to produce what two other types of energy

heat and light

a spring stores energy as

potential energy (elastic)

what form of energy allows you to see yourself in a mirror

light

potential energy is always greater than kinetic energy in a system with

friction

energy is never

created or destroyed

where is the skier’s potential energy the lowest

at the bottom of the hill

when you drop your earbuds

potential energy is converted to kinetic energy

the formula for potential energy

m x g x h

the formula for kinetic energy is

1/2 m v ²

einstein’s equation means

mass and energy are related
