Q. Unmanned aerial vehicles (UAVs) have found diverse applications. Which of the following is the fundamental principle behind the operation of unmanned aerial vehicles (UAVs)?
1.Aerodynamics
2.Hydrodynamics
3.Thermodynamics
4.Quantum Mechanics
Select the correct answer using the codes given below:
Answer: A
Notes:
Explanation – Unmanned aerial vehicles (UAVs), also known as drones, are aircraft that fly without a human pilot on board. They can be controlled remotely or programmed to fly autonomously. UAVs operate on the principle of aerodynamics, which is the study of how air moves around objects. UAVs use their wings and propellers to create lift, which is the force that counteracts gravity and allows them to fly. In addition to aerodynamics, UAVs also use other principles of physics, such as thrust and drag, to fly.
