What is the thermal energy of an object? the total kinetic energy of its particles the total potential energy of its particles its total temperature the total kinetic and potential energies of its particles

Which statement describes a scientific theory? A theory states how something behaves without explaining why. A theory is a proven fact that cannot be changed. A theory changes based on new observations and testing.

What are the differences between deterministic forces and thermal agitation?

What causes the acceleration to increase or decrease?
