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
Itâs in an organismâs cells where all this energy is spent. In some cells, as much as half of a cellâs energy output is used to transfer molecules across the cell membrane, a process called âactive transport.â. Cell movements require energy and thousands of energy-hungry chemical reactions go on in every living cell, every second, every day.
