A scatterplot is used to represent a correlation between two variables. There are two types of correlations: positive and negative. Variables that are positively correlated move in the same direction, while variables that are negatively correlated move in opposite directions.
Thermal energy, or heat, is the energy that comes from the movement of atoms and molecules in a substance. Heat increases with increases in the speed that these particles move. Geothermal energy is the thermal energy in the earth. Motion energy is energy stored in the movement of objects
The flow of energy, such as heat or an electric charge, through a substance. In heat conduction, the energy flows by direct contact of the substance's molecules with each other. Although the molecules vibrate, they do not change position in the transfer of energy.
