Free Fall

The video tutorial explains the concept of acceleration and freefall, emphasizing that objects falling towards Earth accelerate due to gravity. It distinguishes between freefall, where only gravity acts on an object, and situations where other forces, like air resistance, are present. The moon is used as an example of an object in freefall, maintaining its orbit due to its tangential speed and distance from Earth. The tutorial also clarifies the difference between the acceleration due to Earth's gravity (small g) and the universal gravitational constant (capital G). It highlights that gravitational acceleration is independent of an object's mass, meaning all objects accelerate at the same rate in freefall.
