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
â¢ Mechanical energy is the ordered movement of the molecules as a single unit. Thermal energy is the random movement of the molecules. â¢ Mechanical energy can be 100% converted to thermal energy, but thermal energy cannot be fully converted to mechanical energy. â¢ Thermal energy cannot do work, but mechanical energy can do work. â¢ Mechanical energy has two main forms, namely kinetic energy and potential energy.
