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 contact between two objects. Examples of non-cont

  What is Reusable Launch Vehicle   Recently ISRO (Indian Space Research Organization) conducted a test to the landing of Reusable Launch Vehicle. It is a milestone achievement for ISRO and INDIA . From this test , ISRO becomes in the list of countries having reusable launch space flight. Here we look on about the reusable launch vehicles.           A reusable launch vehicle (RLV) autonomous landing mission refers to the ability of a rocket or spacecraft to return to earth and land autonomously, without the need for human intervention. This is an important capability for reusable launch vehicles, as it allows them to be reused for multiple missions, reducing the overall cost of spaceflight.  In a reusable launch vehicle autonomous landing mission, the spacecraft or rocket must be able to navigate through the earth's atmosphere and make course corrections as needed to ensure a safe landing. This typically involves a combination of onboard sensors and computers systems, as well as so
