Force :-

✔A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects.

In SI base units: kg·m/s2

Other units: dyne, poundal, pound-force, kip, kilo pond

SI unit: Newton

Derivations from other quantities: F = m a

Pressure :-

✔Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure is the pressure relative to the ambient pressure. Various units are used to express pressure.

In SI base units: 1 N/m2, 1 kg/(m·s2), or 1 J/m3

Derivations from other quantities: p = F / A

Common symbols: p, P

Dimension: M L−1 T−2

SI unit: Pascal
