उत्तर
- Definition: Gravitational force is a natural force that pulls two objects toward each other. It's the reason why objects fall to the ground on Earth and why planets orbit around the Sun.
- How it Works: The larger the mass of an object, the stronger its gravitational pull. That’s why Earth’s gravity is stronger than the gravity of a small object like a pebble.
- Examples: The force that keeps us from floating into space, The reason planets stay in orbit around the Sun.
- Importance: Gravitational force is essential for maintaining the structure of the universe. Without it, everything would drift apart!

Read the passage given below and answer the questions that follow
Humans have long been fascinated by fiction. We experience excitement in assigning supernatural power to imaginary characters in fictional stories – and so we have Spider man, Batman, He–man, Titans and many more. The ‘Cyborg’ was an offshoot of such wild imagination of humans to invest our species with superhuman powers. Today, the Cyborg is no more an imaginary organism. We are living in a world where a sizeable population of humans have merged their bodies with technological implants. The term ‘Cyborg’, short for ‘cybernetic organism’, was coined to describe a man, whose body is implanted with technological devices to supplement and substitute body functions.
Cyborgs include people with cardiac pacemakers, contact lenses, bionic ears and eyes, prosthetics and so on. In other words, a cyborg is partly human and partly machine. The technological innovations in the field of medicine and healthcare augment humans with machines, producing a beta version of the human body. The advent of brain machine interfaces is certain to blur the boundary between humans and machines. Scientists are working hard to find a technique for age reversal too. People do not want to die, so mankind is striving to get to the final frontier, which is development of machines and devices that would accord man immortality.
The needs of humans are not limited. As time passes, food habits change, thinking patterns change, and even appearances change. We are about to travel by driverless, fully automated vehicles. Computers and smart phones have become our masters. The more we depend and merge with technological advancements, the more the humanness in us slowly erodes. Intelligence is sought to be infused into machines and robotics are designed in such a way to give man a virtual human companion. The field of artificial intelligence is overtaking the human brain and many fear that it could even harm the human race. Despite certain limitations and potential threats, many believe that cyborgs will be the next step in the evolution of mankind. The amalgamation of man and machine is sure to add a new dimension to the life of mankind and this will prove to be the ‘biggest evolution in Biology’ since the emergence of life, four billion years ago.
