#scienceblr notes

-- energy can be converted from one form to another

-- in any energy conversion, the total amount of energy before the conversion is equal to the total amount after the conversion; this is the principal of conservation of energy

-- energy can be transferred by a variety of means

-- energy in conversions could appear in some amounts as unwanted energy, such as waste heat

-- G.P.E = gravitational potential energy

-- G.P.E formula = mgh

-- K.E. = kinetic energy

-- K.E. formula = 1/2mv^2
