| Summary: | The informational re-interpretation of the basic laws of the mechanics exploiting the Landauer principle is suggested. When a physical body is in rest or it moves rectilinearly with the constant speed, zero information is transferred; thus, the informational affinity of the rest state and the rectilinear motion with a constant speed is established. Inertial forces may be involved in the erasure/recording of information. The analysis of the minimal Szilard thermal engine as seen from the noninertial frame of references is carried out. The Szilard single-particle minimal thermal engine undergoes isobaric expansion relative to accelerated frame of references, enabling the erasure of 1 bit of information. The energy Δ<i>Q</i> spent by the inertial force for the erasure of 1 bit of information is estimated as <inline-formula> <math display="inline"> <semantics> <mrow> <mi mathvariant="sans-serif">Δ</mi> <mi>Q</mi> <mo>≅</mo> <mfrac> <mn>5</mn> <mn>3</mn> </mfrac> <msub> <mi>k</mi> <mi>B</mi> </msub> <mover accent="true"> <mi>T</mi> <mo stretchy="false">¯</mo> </mover> </mrow> </semantics> </math> </inline-formula>, which is larger than the Landauer bound but qualitatively is close to it. The informational interpretation of the equivalence principle is proposed: the informational content of the inertial and gravitational masses is the same.
