    Energy is transferred in solids by conduction, which means that A) heat travels in both directions. Eliminate B) heat travels from the cooler object to the hotter object. C) heat travels from the hotter object to the cooler object. D) heat does not travel between objects of different temperatures.

    \[Kinetic energy = \frac{ 1 }{ 2 } mV ^{2}\] When it goes up the velocity reduces thus the kinetic energy decreases. \[Potential energy = mgh\] When going up the height increases so the potential energy increases. !!!!

    sang lol im in 8th and here is my next question During the day, the temperature of the sand in a desert rises as the sand is heated by the sun. After the sun sets, the sand cools. What happens to the heat energy in the sand as it cools? A) It is destroyed. B) It is used by the sand to do work. C) It goes back into the sun, completing the cycle. D) It is transferred to the air via the process of radiation.

    Heat energy cannot be destroyed. So that's wrong so I will go with D

    An example of mechanical energy being converted into heat energy is A) the sun. B) a generator. C) a Snickers bar. D) rubbing your hands together.

    its obviously not sun !!! Generator converts mechanical energy into electrical energy.
