The swan was seen as a traditional symbol of beauty and grace in ancient Greece, and was sacred to Aphrodite. The swan was also sacred to Apollo, the god of music (among other things), in Greek mythology. At the time, the people believed that the swan sang a sweet and beautiful song when people died.
For example, in case of monatomic gas it is just a kinetic energy of motion of atoms of gas as measured in the reference frame of the center of mass of gas. In case of molecules in the gas rotational and vibrational energy is involved.
A system possesses energy if it has the ability to do work. Work shifts energy from one system to another. Energy isâ¦ a scalar quantity, abstract and cannot always be perceived, given meaning through calculation, a central concept in science. Energy can exist in many different forms. All forms of energy are either kinetic or potential. The energy associated with motion is called kinetic energy. The energy associated with position is called potential energy. Potential energy is not stored energy. Energy can be stored in motion just as well as it can be stored in position.
