Force and Pressure are the concepts acting simultaneously on the body in motion. The force is nothing but the interaction between any two bodies or the push or pull between them while the pressure tells how much is the push or pull the body experiences when force is applied over a particular area.** **

Pressure

Pressure is expressed as force per unit area given as

F = Force applied by the body,

A = Total area of the object.

Where,

h is the height,

h is the height,

g is gravity.

Below are problems based on pressure which may be helpful for you.

Given: Mass m = 60 kg,

Radius r = $\frac{D}{2}$ = $\frac{1.5 \times 10^{-2}}{2}$ m

Pressure is given by P = $\frac{F}{A}$

Force F = mg and Area A = $\pi$ r

P = $\frac{mg}{\pi r^{2}}$

= $\frac{60 \times 9.8}{3.142 \times (0.75 \times 10^{-2})^{2}}$

= 3.32 $\times$ 10

(Density of water = 1000 kg / m

Given: Density of water = 1000 kg / m

Acceleration due to gravity = 9.8 m/s

The pressure is given by P = $\rho$ $\times$ g $\times$ h

= 1000 $\times$ 9.8 $\times$ 1m

= 9800 Pascal.
