Forms of Energy
Playing a trumpet
Sound Energy
When energy goes from one object to another without changing form.
Transfer
Resource that is replaced fast as or faster than it is used.
Renewable Energy
When an object cools down, the particles in that object will ___________.
Thermal Contraction
Picture on a wall
Gravitational Potential Energy
When energy is "lost" in a transformation, the energy that is lost is _______________ energy.
thermal
Solar energy takes __________ energy and changes it into electrical energy
radiant
You can feel the heat from the fire without touching it.
Radiation
Ability to cause change.
Energy
Gears moving in a clock
Mechanical Energy
When one object changes it's energy into a different form of energy
Resource that cannot be replaced or is being used faster than can be replaced in nature
When the particles of an object move quickly increasing the volume of the object.
Thermal Expansion
Measurement of the amount of thermal energy or the average thermal energy in an object.
Outlet
Electric Energy
Energy cannot be created or destroyed, it can changed into different forms of energy.
Law of Conservation of Energy
Wind turbines move creating ___________ energy to then be converted into electric energy by use of a generator.
kinetic or mechanical
In science we measure temperature in __________.
Celsius
Transfer of thermal energy by collisions between particles in different objects.
Conduction
Digestion
Chemical Energy
When we say that energy that energy transformations are "inefficient," we mean that not all of the energy is ____________.
usable
When using fossil fuels, we begin with ____________ energy and release it by burning it and eventually changing it into electric energy.
chemical
When the water in the water in the bottom of a beaker is hotter than the water on top. The hot water will rise and the cold water will sink.
Convection
Movement of thermal energy from an area of higher thermal energy to an area of lower thermal energy.
