Hello Beena,
Since you have not mentioned what does the letter p mean in physics, I would give you all possible formulas in physics related to the letter P.
Momentum p is given by p=mv, where m is the mass and v is the velocity of the particle.
Pressure P is given by P=F/A where F is the force and A is the area.
