define pressure .what is tje relation between pressure and force and area?state the unit in which pressure is measured
Answers
Answer:
Pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. .In SI units, pressure is measured in pascals; one pascal equals one newton per square metre. Atmospheric pressure is close to 100,000 pascals.
The pressure is a concept which rises when force is applied to a unit area; in simple words, the pressure is the force per unit area. According to the formula P = F/A, the pressure is directly proportional to the force, i.e. if force is more, the pressure will also be more.
The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2)

Answer
Difine 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.
