Air resistance

The video tutorial explains air resistance, also known as drag, which acts against the direction of movement. It is caused by collisions between an object's surface and surrounding air particles. Parachutes are designed to maximize air resistance, slowing the descent of a person or object in freefall. The large cross-sectional surface area of a parachute increases frictional force, aiding in a safe landing.
