The force that keeps us grounded on Earth is gravity.

Characteristics of Gravity

  • Universal Force - Gravity is a fundamental force that acts between any two masses. It attracts objects toward each other and is responsible for holding planets, stars, and galaxies together.
  • Proportional to Mass - The strength of the gravitational force between two objects depends on their masses. Larger masses exert a stronger gravitational pull.
  • Inverse Square Law - The force of gravity decreases with the square of the distance between the centers of two masses. As the distance increases, the gravitational force weakens.

Importance of Gravity

  • Maintains Orbit - Gravity keeps Earth and other planets in orbit around the Sun, which is essential for sustaining the conditions necessary for life on our planet.
  • Keeps Atmosphere Intact - It holds the Earth's atmosphere close to the surface, ensuring that gases like oxygen and nitrogen are available for breathing and supporting life.
  • Facilitates Water Cycle - Gravity drives the water cycle by causing precipitation to fall back to Earth, leading to rivers, lakes, and oceans that are essential for drinking water, agriculture, and various ecosystems.
