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.
Unit 26 Types of Energy Energy can neither be created nor destroyed. Energy changes from one kind to another. The total energy of an object never changes. Anything that has mass and movement has kinetic energy.The kinetic energy of an object in this case is given by the relation: KE = (1/2)mv2 m=mass of the object V=velocity of the object The greater the mass or velocity of a moving object, the more kinetic energy it has.ind power uses mechanical energy to help create electricity. Potential energy + Kinetic energy = Mechanical energy Mechanical Energy Summary Gravitational PE Elastic PE The energy of motion mgh Energy that is stretched or compressed.
