Free fall is a fundamental concept in physics that describes the motion of an object under the sole influence of gravity.

Definition
Free fall is the motion of an object that is falling towards the ground or another celestial body, with no external forces acting upon it, except for gravity.

Characteristics
1. Acceleration: Objects in free fall accelerate towards the ground at a rate of 9.8 m/s² (on Earth).
2. Constant Acceleration: The acceleration due to gravity is constant, meaning the object's velocity increases at a steady rate.
3. No Air Resistance: In ideal free fall, air resistance is negligible, allowing the object to fall freely.

Examples
1. Dropping Objects: Dropping a ball or stone from a height is a classic example of free fall.
2. Skydiving: Skydivers experience free fall before deploying their parachutes.
3. Spacecraft: Spacecraft can experience free fall during certain phases of their journey.
