Energy

QuestionAnswer
the process of burning a fuel is called combustion
potential energy that depends on height is called gravitational potential energy
kinetic energy increases as both mass and velocity increase
unlike kinetic energy, potential energy is stored
the rate at which energy is transferred is called power
an example of something that stores chemical energy is a match
a change from one form of energy into another is called an energy transformation
energy stored in the nucleus of an atom is called nuclear energy
the type of energy stored by fossil fuels such as coal is chemical potential energy
the total potential and kinetic energy of the particles in an object is called thermal energy
you calculate an object's mechanical energy by adding its kinetic and potential energies
the type of energy a spinning turbine has is mechanical energy
visible light is an example of electromagnetic energy
the energy associated with motion is called kinetic energy
fossil fuels contain energy that originally came from the sun
the scientist who suggested that energy can be created under certain conditions was Einstein
when generators are spun by turbines, they produce electricity
the formula, weight x height, is used to calculate potential energy
energy is measured in units called joules
something that has kinetic energy must be something that is moving
an example of a fossil fuel is petroleum
the ability to do work is called energy
the law of conservation of energy states that when one form of energy is converted into another, no energy is destroyed in the process
when fossil fuels are burned, their chemical potential energy is converted into thermal energy
