Concept Explanation
 

Thrust

Thrust: We have just defined pressure in terms of force. Pressure can also be defined in terms of another force called thrust. The force acting on a body perpendicular to its surface is called thrust. Actually, thrust is the total force acting on the surface of a body. So, we can also define pressure as thrust per unit area.

Pressure = frac{Thrust }{ Area.}

Examples of thrust in daily life :

1. Thrust is to move forward as a crowd entering a stadium.

2. Thrust is to force one's self into a conservation.

3. An example of thrust is a fish being expelled from the ocean by a strong wave.

4. It is easy to carry or to walk with high heels, and cause thrust acting here .

5. A pistole engine can produce thrust in its own.
