Air resistance is another force. It is very important for many animals. Force example, air resistance allows the royal air force to jump out of planes without hurting themselves and it allows birds to glide through the air. As gravity pulls an object down, air resistance works in the opposite direction to reduce the speed at which the object is falling.
Fun fact: The larger the surface area of an object, the slower it falls.
Did you know? Sea gulls have a large surface area from their wings in comparison to their body weight. This allows them to glide up and down using air resistance.
