Here's why:
* Freefall means the only force acting on the object is gravity.
* This means there is no air resistance, no wind, no propulsion, just the constant pull of gravity.
It's important to note that:
* Freefall doesn't necessarily mean the object is falling downwards. An object thrown upwards is also in freefall as long as only gravity is acting on it.
* Freefall is an idealized concept. In reality, air resistance is always present, but in many cases, it's negligible enough to consider an object in freefall.
