Flow of Energy - Coggle Diagram
Flow of Energy
Law of Conservation of Energy
states that energy can never be created nor destroyed
proven in many scientific experiments
can be transformed
Ex: gravitational--> kinetic
Energy Source
aka resource
provides usable energy
accessible and attainable
Energy Sink
occurs when source is no longer accessible/attainable
remains in potential energy form until the energy can be released
Energy
the ability to do work
needed for survival of organisms
required for motion
Primary Energy Forms
Potential Energy
energy that is stored and could potentially be transferred to another form
Gravitational Potential Energy
measure of potential movement and speed the object could experience if it fell
Kinetic Energy
energy of movement
any object in motion shows it
directly related to gravitational potential
larger/higher the object--> more kinetic energy
bigger and faster = more kinetic energy
Chemical Energy
energy stored in bonds of molecules
seen anytime food or fuel source is used
Thermal Energy
aka heat energy
Released 3 ways
Conduction: heat transfers when to objects touch
Convection: heat transfers as warm gas/liquid molecules rise and the cool ones fall
Radiation: heat moves around particles
particles vibrate; when the particles bump into each other they transfer energy
Sound Energy
move through air in longitudinal waves
source causes vibrations
eardrums pick up vibrations and translate into sounds
more kinetic energy = louder sounds
Electrical Energy
electrons move in current
through wire
