g is Positive.

The video tutorial explains the concept of gravity, focusing on the acceleration due to gravity, denoted as little g, which is positive 9.81 m/s² on Earth. It addresses common misconceptions about gravity's direction and its effects on objects in free fall and projectile motion. Through experiments and examples, the tutorial clarifies that while the force of gravity acts downward, little g is a positive constant used to calculate gravitational force. The video also distinguishes between the acceleration of an object and the acceleration due to gravity, emphasizing their different roles in physics.

Why is it important to distinguish between little g and the acceleration of an object?

What is the difference between the acceleration of an object and the acceleration due to gravity?

What happens to the acceleration of an object when a normal force acts on it?
