What do you mean by free fall?

The gravity of the earth attracts every object towards its centre. When an object is dropped from a certain height, it begins to fall towards Earth’s surface under the influence of gravitational force. Such a motion of an object is called free fall.

Definition

Free fall is defined as when a body is moving only under the influence of the earth’s gravity. Since external force is acting on the ball, the motion will be accelerated. This free-fall acceleration is also known as acceleration due to gravity.

Example

Listed below are a few examples of free fall

  • A stone falling in an empty well
  • The ball is thrown in a projectile motion
  • A spacecraft in continuous orbit
