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. 1  Chemical-Chemical energy comes from atoms and molecules and how they interact. 2  Electrical-Electrical energy is generated by the movement of electrons. 3  Gravitational-Large objects such as the Earth and the Sun create gravity and gravitational energy. 4  Heat-Heat energy is also called thermal energy. 5  Light-Light is called radiant energy. 6  Motion
