Here's why:
* Freefall means the object is only experiencing the force of gravity.
* No other forces are acting on the object, like air resistance or friction.
* This means the object is accelerating at a constant rate, known as the acceleration due to gravity.
Important Note: While we often think of freefall as objects falling straight down, it can also apply to objects thrown upwards, or moving horizontally in a curved path due to gravity.
