Science
measure of the average kinetic energy of all the particles that make up an object
sum of the kinetic and potential energy of the particles that make up an object
amount of heat needed to raise the temperature of 1kg of a material
transfer of thermal energy by collisions between the particles that make up matter
The study of energy transformations that occur in a collection of matter.
device used in a active solar eating system that transforms radiant energy from the Sun into thermal energy
a material through which thermal energy moves slowly
transfer of energy by electromagnetic waves
transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from one place to another
Transferring charge by touching or rubbing
What is static electricity?
Accumulation of excess electric charge on an object
What is law of conservation of charge?
Charge can be transferred but not created or destroyed
What is electric field?
Surrounds an electric charge and exerts a force
What is conductor?
Material through which electrons move easily
What is insulator?
Material through which electrons are not able to move easily.
What is charging by induction?
Rearrangement of electrons caused by a nearby charged object.
What is electro science?
Device that can detect electric charge.
What is electric current?
Net movement of electric charges in a single direction
What is voltage difference?
Related to the force that causes electric charges to flow.
states that if the mechanical energy of a systm is constant, the increase in the thermal energy of the system equals the sum of the thermal energy transferred into the system and the work done on the system
states that energy spontaneously spreads from region of higher concentration to regions of lower concentration
What is electric circuit?
Closed path that electric current follows.
heat engine that burns fuel inside the engine in chambers or cylinders
device that converts some thermal energy into mechanical energy
