Falling Objects and Terminal Velocity: Understanding Gravity, Air Resistance and Factors Affecting Velocity

The video tutorial explores how objects behave under gravity, focusing on Newton's Second Law. It demonstrates calculations of acceleration for a hammer and a feather, showing that all objects fall with the same acceleration if weight is the only force. The concept of air resistance is introduced, explaining how it affects a skydiver's acceleration and leads to terminal velocity. The tutorial also covers factors affecting terminal velocity, such as mass and surface area.
