* Acceleration due to Gravity: The primary force acting on a falling object is gravity, which causes a constant acceleration of approximately 9.8 m/s². This means the object's speed increases by 9.8 meters per second every second.
* Air Resistance: As the object falls, it encounters air resistance. This force opposes the object's motion and increases with speed.
* Net Acceleration: The net acceleration of the falling object is the difference between the acceleration due to gravity and the acceleration due to air resistance. As the object falls faster, air resistance increases, reducing the net acceleration.
Example:
Imagine a skydiver jumping out of a plane. Initially, the skydiver accelerates rapidly due to gravity. As the skydiver's speed increases, air resistance grows. This causes the net acceleration to decrease. Eventually, the skydiver reaches a terminal velocity where the force of air resistance balances the force of gravity, and the net acceleration becomes zero. The skydiver continues falling at a constant speed.
Conclusion:
A falling object can increase in speed while decreasing acceleration because air resistance counteracts the force of gravity. This results in a smaller net acceleration, even though the object is still speeding up.
