P Pressure Physics P Dot (disambiguation)

P Pressure Physics P Dot may refer to:

• 💡

  p·Pressure in physics (pressure times area/pressure–force relation)

  “p·” notation is commonly used in physics for pressure (p), and it may be used with dot products or time derivatives depending on context.

• 💡

  ṗ (p dot): time derivative of pressure in physics

  In many physics/engineering contexts, “ṗ” (p dot) denotes the time derivative of a pressure variable p.

• 💡

  p· (momentum dot product) in physics

  “p·” can also mean a dot product involving the momentum vector p, often written as p·v or p·E in equations.
