Unit 2 Energy Practice Quiz Flashcards
Energy
Energy is the ability to do work/cause change
Kinetic Energy
Kinetic Energy is the energy of motion
Potential Energy
Potential Energy is stored energy or the energy of position
Law of Conservation of Energy
Energy cannot be created or destroyed it can only change forms
Particle Theory of Matter
All matter is made up of many very small particles
Solid
Particles that vibrate in place
Liquid
Particles that move past each other
Gas
Particles that move everywhere
Temperature
Measures the speed of particles object
Heat
A form of energy of resulting from the vibration, movement,collision of form and molecules
Expansion
Temperature increases particles expand and take up more space
Contraction
Temperature decreases particles contract and take up less space
Conduction
The transfer of heat between substance that are in direct contact with each other
Convection
The transfer of heat by the up and down movement of particles in liquids or gases
Radiation
The transfer of heat when electromagnetic waves travel through empty spaces
