work: the transfer of energy to an object by the application of a force that causes the object to move in the direction of the force.
power: quantity that measures the rate at which work is done or is transformed
mechanical advantage: quantity that expresses how much a machine multiplies force or distance
simple: one of the six BASIC types of machines
compound: machine made of more than one simple machine
require:to need
energy: ability to do work
potential: stored energy
kinetic: energy in motion
mechanical: amount of work an object can do
efficiency: quantity that measures the ratio of useful wok output to work input
joules: energy is measured in
ignore: to refuse to notice
temperature: measurement of the average kinetic energy of the molecules in an object or system
thermometer: device used for measuring the temperature.
absolute zero: lowest possible temperature
heat: thermal energy
transfer: movement from one place to another
thermal conduction: reasonably straightforward concept when you are discussing heat loss
convection:up & down movements of gases & liquids
radiation: travel through empty space
specific heat: the amount it takes to raise 1g of a substance by 1°C
conduct: direct contact
entropy: measure of a system’s thermal energy per unit temperature
heat engine: uses energy provided in the form of heat to do work
