Here's why:
* Free Fall: This term specifically refers to the motion of an object where the only force acting on it is gravity. This means air resistance (drag) is negligible.
* Gravity: This is the force of attraction between any two objects with mass. In the case of free fall, the object is being pulled towards the Earth's center of mass.
Important Note: In real-world situations, air resistance is always present to some degree. However, if the air resistance is small enough compared to the force of gravity, we can approximate the object's motion as free fall.
