Work and Kinetic Energy

Authors: M. R. Carvajal
Comments: 4 pages,

We point to a problem with the current generally accepted idea that work W = ∫ F⋅dx transfers kinetic energy KE = (1/2)mv2, showing that with exactly the same amount of work, done through a pulley or a lever, different amounts of kinetic energy can be imparted to objects of different masses. We do this without violating the laws of classical mechanics, or the work-kinetic energy theorem W = ΔKE.

Laser Boost of a Small Interstellar Ram Jet to Obtain Operational Velocity. Implications for the DM Rocket/ram Jet Model

Authors: Andrew Beckwith
Comments: 12 pages. Re formatted with font size 12 . Document to be delivered to meeting in Scottsville, Arizona, November 2nd.

In other conference research papers, Beckwith obtained a maximum DM mass/ energy value of up to 5 TeV, as opposed to 400 GeV for DM, which may mean more convertible power for a dark matter ram jet. The consequences are from assuming that axions are CDM, and KK gravitons are for WDM, then ρWarm-Dark-Matter would dominate not only structure formation in early universe formation , but would also influence the viability of the DM ram jet applications for interstellar travel. The increase in convertible DM mass makes the ram jet a conceivable option. This paper in addition to describing the scientific issues leading to that 5 TeV mass for DM also what are necessary and sufficient laser boost systems which would permit a ram net to become operational.

Energy Functions Describing Kinematical Transformations of Moving Mechanical Systems

Authors: Adem Bilgin
Comments: 16 pages

Kinematical transformations are expressed as time independent and time dependent functions of work and energy to be employed in motions of mechanical systems. Relations between the kinematical parameters of moving mechanical systems and energy transformations occurring in them are also considered.
