Energy
Question | Answer |
---|---|
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 |
