Centripetal force
Definition:Centripetal force is the force that keeps an object moving in a circular path. it acts toward the center of the circle around which the object is moving.
Why things revolve around Earth without collapsing?
1. Gravitational Force = Centripetal Force
The Earth’s gravity pulls the Moon, satellites, or any orbiting body toward its center.
This pull acts as the centripetal force, keeping the object in orbit.
The object’s speed prevents it from falling straight down.
The object is moving forward due to its velocity.
Gravity constantly pulls it inward, changing its direction — not its speed.
As a result, it keeps falling around Earth, forming a circular or elliptical orbit instead of crashing.
