What is kinetic energy?
Plants transform _________ energy into chemical energy.
What is radiant.
The energy stored in the nucleus of an atom
What is Nuclear Energy?
A mountain climber lifts a 6.00-kg pack. What is the gravitation potential energy of the pack at 7.00 m above the base of the cliff? Use the equation for GPE to answer the question. Remember that g is the acceleration due to gravity, which is 9.8 m/s2.
GPE =mgh
What is 412J
If GPE = mgh, then GPE of the pack is
6.00 kg x 9.8 m/s2 x 7.00m = 412 J
Comes from the heat generated inside Earth.
