Force vs Pressure
Force V/S Pressure "जोर लगाके हईया" जब हम कोई मेहनत का काम करते है तो ये शब्द मुँह से जरूर निकलता है वैसे क्या आपको पता है प्रेशर नाम भी इसी से जुड़ा सा लगता है पर वो विज्ञान की नजरो में अलग है आईये जानते है कैसे ? Force is a physical quantity that describes the interaction between two objects. It is defined as the push or pull that one object exerts on another object. Force is a vector quantity, meaning that it has both magnitude (size) and direction, means if we say the x amount of force is acting then we also tell that the force is acting in which direction. The SI unit of force is the Newton (N). There are two types of forces : Contact forces and non-contact forces. Contact forces are forces that require physical contact between two objects. Examples of contact forces include friction, tension, normal force, and air resistance. non-contact forces, also called action-at-a-distance force, do not require physical conta...
