specific heat
amount of thermal energy it takes to increase the temperature of 1 kg of material by 1 degree C.
thermal conductor
material through which thermal energy flows easily
shaft attached to a wheel so that both rotate together
wheel & axle
stored energy
potential energy
represents the average kinetic energy of the particles that make up a material or object
temperature
pulley
grooved wheel with a rope or cable wrapped around it
potential energy
stored energy
convection current
movement of fluidsin a cycle because of convection
ratio of output work to input work
efficiency
pivots around a fixed point
lever
transfer of thermal energy of the movement of particles from one part of a material to another
convection
does work through use of one movement
simple machine
inclined plane wrapped around a cylinder
screw
movement of fluidsin a cycle because of convection
convection current
two or more simple machines working together
complex machine
wheel & axle
shaft attached to a wheel so that both rotate together
lever
pivots around a fixed point
conduction
transfer of thermal energy between materials because of collisions between particles.
transfer of thermal energy from one material to another by electromagnetic waves
radiation
material through which thermal energy does NOT flow easily
thermal insulator
transfer of energy that occurs when a force makes an object move in the direction of the force while the force acts on the object
work
kinetic energy
object that has energy because it is in motion
thermal energy
sum of the kinetic energy and potential energy of the particles that make up an object
the movement of thermal energy from a warmer object to a cooler object
