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
to move matter in a direction it would no move if left alone. required by all organisms to survive. Energy exists in two states. kinetic energy. energy of motion. moving objects perform work by causing matter to move. potential energy. stored energy.
