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 is an example of thermal energy. Motion Energy is the movement of objects and substances from one place to another. According to . Newtonâs Laws of Motion, objects and substances move when a force is applied. Wind is an example of motion energy. Sound Energy is the movement of energy through substances in longitudinal (compression/rarefaction) waves. Sound is produced . when a force causes an object or substance to vibrate. The energy is transferred through the substance in a wave. Introduction to Energy
