What is gravitation ?

Gravitation can b edefine as the force that pulls objects with mass toward each other.

1. Keeps Us Grounded: Gravity pulls everything towards the center of the Earth, keeping people, animals, and objects on the ground.


2. Causes Things to Fall: When you drop an object, gravity pulls it down towards the Earth.


3. Shapes and Holds Atmosphere: Gravity keeps the Earth's atmosphere from drifting into space, allowing us to breathe.


4. Influences Water Flow: Gravity causes rivers to flow downhill, rain to fall, and creates ocean tides influenced by the moon's gravity.


5. Planetary Orbits: Gravity keeps planets in orbit around the sun. Without gravity, planets would drift off into space.


6. Moon's Orbit: Gravity keeps the moon orbiting around the Earth, affecting tides and stabilizing the planet's rotation.


7. Formation of Solar System: Gravity pulled gas and dust together to form the sun, planets, and other bodies in the solar system.


8. Walking and Movement: Gravity provides the force that our muscles work against to move and walk.


9. Sports and Activities: Gravity affects the trajectory of balls in sports like basketball, soccer, and baseball.


10. Engineering and Construction: Gravity influences the design of buildings, bridges, and other structures to ensure they remain stable.


11. Satellites and Orbits: Understanding gravity helps in placing satellites in orbit for communication, weather forecasting, and navigation.


12. Space Exploration: Gravity assists in planning spacecraft trajectories for missions to other planets and moons.


13. Timekeeping and Clocks: Gravitational time dilation, predicted by Einstein's theory of relativity, affects the accuracy of satellite-based clocks and is accounted for in GPS systems.

What is Weightlessness ?

Weightlessness is the sensation or condition that occurs when there is no force of gravity acting on a body, or when the effects of gravity are not felt.

What is Satellite ?

An object that orbits a planet or star, which can be natural (like moons) or artificial (like the Hubble Space Telescope).

What is Space travel ?

Space travel refers to the act of traveling into or through outer space.
Human Spaceflight: This involves sending astronauts into space, either to orbit the Earth, visit the Moon, or explore other planets.
