Science: Unit 4 Flashcards
Energy from random motion of molecules
Thermal Energy
Energy stored in chemical bonds of compounds
Chemical Energy
Converts chemical energy to kinetic energy
Internal Combustion Engine
Depends on mass, phase and tempature
Thermal Energy Dependence
Stored Energy due to position or properities
Potential Energy
Radiant energy travelling in waves
Electromagnetic Energy
Kinetic energy converted to electrical energy
Wind energy conversion
Material reducing thermal energy transfer
Insulator
PE=mass x gravity x height
Gravitational Potential Energy
Q = m · c · ΔT for heat calculation
Heat Absorption Formula
Energy moves between different forms.
Energy Transfer
Average kinetic energy of particles.
Tempature
Material allowing easy thermal energy transfer.
Conductor
Resources that cannot be quickly replaced.
Nonrenewable Energy Resources
Energy due to motion or position of an object.
Mechanical Energy
Ability to do work or cause change.
Energy
Energy cannot be created or destroyed.
Conservation of Energy
Transfer of thermal energy due to temperature difference.
Heat
What is kinetic energy?
Energy of moving matter-anything that is moving as KE
Mechanical Energy
Energy possessed by an object due to it’s motion or position
What is Electrical Energy?
Energy that results from the movement of charged particles, such as electrons, through a combustion
What is electromagnetic Energy?
Radiant energy that travels in waves at the speed of light
What is nuclear energy?
Energy released from the nucleus, the core of atoms, made up of protons and neutrons
What is a non-renewable resource?
Natural resources that cannot be replaced as quickly as they are used up
