• Physics on a turntable
  04-May-20210 Comments
  Tags: Science

  A turntable (merry-go-round, roundabot, carousel) is a simple example of non-inertial reference frame. I discuss some simple examples of motion in the inertial as well as rotating frame.

• Fictitious forces in rotating systems
  02-May-20210 Comments
  Tags: Science

  A non-inertial reference frame is a frame of reference that undergoes acceleration with respect to an inertial frame. Fictitious forces explain movement of bodies in non-inertial reference frames. In this article I discuss rotating systems.

  Enthalpy is defined as the internal energy of a system plus the product of pressure and volume.
• Heat
  06-Nov-20190 Comments
  Tags: Science

  Heat represents a transfer of energy.
