If I drop 2 of the same object but different mass like a pocket book and a encylopedia, they drop at the same time. Why is that? Anyone can get a detailed explanation? Thanks!

This is because of the force of gravity. All objects experience the same acceleration due to gravity regardless of their mass. This is known as the principle of equivalence.
No, the shape of an object does not affect its falling time as long as there is no air resistance. In a vacuum, all objects will fall at the same rate regardless of their shape or size.
Galileo Galilei was the first to experimentally demonstrate that objects of different mass fall at the same time. He dropped two objects of different masses from the Leaning Tower of Pisa and observed that they reached the ground at the same time.
Yes, air resistance and the presence of other forces such as wind can affect how objects fall at the same time. In a vacuum, where there is no air resistance, all objects will fall at the same rate regardless of their mass.
Understanding this concept is important in the fields of physics and engineering. It allows us to accurately predict the motion of objects and design structures that can withstand gravitational forces. It also helps us understand the behavior of objects in space and on other planets with different gravitational strengths.
