1. Acceleration:
* The most important characteristic is that the body accelerates due to gravity. This acceleration is constant near the Earth's surface and is denoted by g, approximately 9.8 m/s².
* This means that the velocity of the falling body increases by 9.8 meters per second every second.
2. Velocity:
* If the body starts from rest (initial velocity = 0), its velocity increases linearly with time.
* The equation for velocity at any time 't' is: v = gt
* This means that the velocity of the falling body increases proportionally to the time it has been falling.
3. Displacement:
* The distance the body falls increases non-linearly with time. This is because the velocity is increasing.
* The equation for displacement at any time 't' is: d = (1/2)gt²
* This means that the distance the body falls increases quadratically with the time it has been falling.
Important Considerations:
* Air resistance: In reality, air resistance plays a significant role in the motion of falling bodies. This force opposes the motion and causes the object to reach a terminal velocity (a constant speed) after a certain time.
* Assumptions: The above description assumes that the body falls in a vacuum, where air resistance is negligible.
Overall, the motion of a freely falling body is a simple yet fundamental example of uniformly accelerated motion. Understanding this motion is crucial for many physics concepts and applications.
