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
Mechanical energy is the energy possessed by an object due to its motion or its position. Well, that seems simple enough, but what is energy? Energy is the ability to do work, where work is the movement of an object when a force is applied to it. For example, a person doing push-ups is doing work by applying force to the floor.
