Forces and Motion

physical science

Force push or pull
Work energy that causes a change in motion
Law of Conservation of Energy Energy cannot be created or destroyed, it can only transform
Potential Energy the stored energy due to position
Kinetic Energy the energy of motion
Elastic Potential Energy stored energy that is compressed and/or stretched
Gravitational Potential Energy the stored energy due to height
Mechanical Energy the sum of potential and kinetic energy
Newton the measurement of force
Heat thermal energy moving from a region of higher temperature to a region of lower temperature
Friction the thermal energy due to objects rubbing together.
Waste Energy energy not being used
Thermal Equilibrium Two objects at the same temperature
Conduction the transfer of thermal energy due to collisions between particles in matter.
Thermal conductor a material in which thermal energy moves quickly, such as metals
Thermal insulator a material in which thermal energy moves slowly, such as air
Convection the transfer of thermal energy by the movement of particles from one part of a material to another. (hot rising and cold sinking)
Radiation the transfer of thermal energy from one object to another by electromagnetic waves.
Sound energy requires a medium (vibrating objects), cannot travel through a vacuum
Nuclear energy stored and released in the nucleus of an atom
