The sum of potential and kinetic energy is known as total mechanical energy.
True
False
I.e. Mechanical energy includes both kinetic and potential energy.
Which of the statements are correct
1) the sum of the kinetic energy and potential energy is called the total mechanical energy
2) the sum total of energy in a system is constant
Moving train has its complete mechanical energy in the form of potential energy only. State true or false.
By definition, the total kinetic energy is the sum of translation, rotational and vibrational kinetic energies for monoatomic gases only the translational K.E. is counted. True or False ?
