Gravity's Influence on Falling Objects

Dana, a physics teacher, explains the concept of acceleration due to gravity, which is 9.8 meters per second squared. Using the example of a coconut falling from a tree, Dana illustrates how gravity causes an object's speed to increase by 9.8 meters per second every second. The video aims to help viewers understand the significance of this acceleration value and its impact on objects in free fall.
