scalar n vector.

JEE Advanced 2015 Questions › General Physics questions › scalar n vector.

could anyone pls tell me why is pressure a scalar quantity while it is given as P = F/A where F force is a vector quantity and A area is a scalar quantity.

Pressure is a scalar quantity because there is no directional component associsated with pressure, just a magnitude. Scalar quantities possess only a magnitude measurement, whereas vector quantities possess a magnitude and a directional measurement.

how would be if you redefine pressure as:

P=F.a(dot prod of Force and Area)
