Explain internal kinetic and potential energies of molecules.

A particle excutes SHM, at what value of displacement are the kinetic and potential energies equal?

What do you mean by energy? Explain kinetic and potential energy with examples.

How does the (a) average kinetic energy (b) average potential energy of molecules of a substance change during its change in phase at a constant temperature, on heating ?

Statement-1: In kinetic theory of gases, we do not take into account the change in gravitational potential energy of the molecules. Statement-2: The internal energy of a gas depends on the interaction between gas molecules. This interaction is not affected by the change in gravitational potential energy of the molecules.

"We do not take into account the changes in gravitational potential energy of the molecules also in the kinetic theory of gases". Why?

Assertion: In a simple harmonic motion the kinetic and potential energy becomes equal when the displacement is (1)/(sqrt(2)) time the amplitude Reason: is SHM kinetic energy is zero when potential energy is maximum

Name the following Kinetic and potential energy together

Pressure of a gas at constant volume is proportional to a) total internal energy of the gas b) average kinetic energy of the molecules c) average potential energy of the molecules d) total energy of the gas

Kinetic energy of molecules is highest in

Assertion: y-x graph of a transverse wave on a string is as shown in figure. At point A potential energy and kinetic energy both are minimum. Reason : At point B kinetic energy and potential energy both are maximum.
