Basically, the "push back" of the air against the object moving forward. It acts similar to friction, except the resistance is based on the shape of the object instead of the interaction of the object and the ground
Air resistance is the pushing of air against an object that is moving. Both the air and the object rub together and this slows the down the object and making it use more energy to reach a required speed. If an object moves faster, the greater the air resistance it encounters.
