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
As a collection of classical material particles, temperature is a measure of the mean energy of motion, called kinetic energy, of the particles, whether in solids, liquids, gases, or plasmas. The kinetic energy, a concept of classical mechanics, is half the mass of a particle times its speed squared.
