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
Energy of motion (kinetic energy) is produced, as the ball accelerates downward. If we think of the sun as a huge sphere of gases, each atom in the gas feels a net attraction to the center of the sphere. So all the atoms have a tendency to fall in toward the center.
