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
kinetic energy, n a property of a particle that describes the energy of motion and directly correlates with the particle's rate of motion. For example, transfer of gaseous particles is an important factor in the field of aromatherapy.
