Pressure: Definition and Explanation
Definition: Perpendicular force acting per unit area is called pressure.
Explanation: Pressure is the force exerted per unit area. It is measured in units of newtons per square meter (N/m2) or pascals (Pa). Pressure can be caused by a variety of factors, such as the weight of an object, the force of a fluid, or the impact of a gas. For example, an elephant standing on a small area exerts a high pressure, while the same elephant standing on a larger area exerts a lower pressure.
Pressure is an important concept in physics and engineering. It is used to describe the behavior of fluids (liquids and gases) and the strength of materials (such as metals and plastics). Pressure plays a role in many everyday processes, such as the operation of hydraulic systems, the measurement of blood pressure, and the performance of airplane engines.
Some common units of pressure are:
- Pascals (Pa): The SI unit of pressure. One pascal is equal to one newton per square meter (N/m2).
- Atmospheres (atm): A unit of pressure commonly used for atmospheric pressure. One atmosphere is equal to the pressure exerted by the weight of the Earth's atmosphere at sea level.
- Pounds per square inch (psi): A unit of pressure commonly used in the United States. One psi is equal to 6895 pascals.
In summary, pressure is the force exerted per unit area and is measured in units of newtons per square meter or pascals. It is an important concept in physics and engineering and is used to describe the behavior of fluids and the strength of materials.

The answer is c)Pressure
As power means that the work done in a unit time.
Work means the energy transferred to displace an object.
Pressure means the force applied on a surface.
Energy means the capacity to do work.
