- Connecting the experimental study of the physical and chemical properties is the immense theoretical edifice termed the kinetic theory of gases.
- But no one can tell whether the study of physiological phenomena in general, and of nervous phenomena in particular, will not reveal to us, besides the vis viva or kinetic energy of which Leibnitz spoke, and the potential energy which was a later and necessary adjunct, some new kind of energy which may differ from the other two by rebelling against calculation" (Bergson, Time and Free Will, Eng.
- 203) show that chemical action is to be referred to the latter of these vectors, but whether Fresnel's or Neumann's hypothesis be correct is only to be decided when we know if it be the mean kinetic energy or the mean potential energy that determines chemical action.
- Ann., 1875), who regarded electricity as consisting of atoms much smaller than those of matter, and supposed that heat was the kinetic energy of these electric atoms. If we suppose that an electric current in a metal is a flow of negative electric atoms in one direction, the positive electricity associated with the far heavier material atoms remaining practically stationary, and if the atomic heat of electricity is of the same order as that of an equivalent quantity of hydrogen or any other element, the heat carried per ampere-second at o C., namely P, would be of the order of 030 of a joule, which would be ample to account for all the observed effects on the convection theory.
- Coulomb pointed out long ago that the resistance of a body to be set in motion was in many cases much greater than the resistance which it offered to continued motion; and since his time writers have always distinguished the "friction of rest," or static friction, from the "friction of motion," or kinetic friction.
- These experiments distinctly point to the conclusion, although without absolutely proving it, that in such cases the coefficient of kinetic friction gradually increases as the velocity becomes extremely small, and passes without discontinuity into that of static friction.
- accelerated from rest, also acquires kinetic energy and so its inertial mass must increase as speed increases.

- Kinetic studies on the nanosecond timescale are also possible using a laser flash photolysis instrument.
- In both cases, we need extensive experimental studies seeking to identify all long-lived polymorphs in order to understand the kinetic factors involved.
- This should ensure that the data-mining analysis could find the most effective correlation between the observed polymorphs and the predicted thermodynamic and kinetic properties.
- Hence, we need to rationalize the kinetic factors that can lead to the observation of metastable polymorphs.

- The energy in a train of waves carried forward with the waves is partly strain or potential energy due to change of volume of the air, partly kinetic energy due to the motion of the air as the waves pass.
- It may, however, be maintained that an ultimate analysis would go deeper, and resolve all phenomena of elastic resilience into consequences of the kinetic stability of steady motional states, so that only motions, but not strains, would remain.
- in the time At, during which the velocity falls from v+2Av to v-2Av, we have (12) RAs = loss of kinetic energy in foot-pounds =w(v+ZOv) 2 /g - w(v - ZOv) 2 /g=wvAv/g, so that (13) As =wvAv/nd 2 pg =CAS, where (14) AS = vAv/g p = vAT, and AS is the advance in feet of a shot for which C =1, while the velocity falls Av in passing through the average velocity v.
