Today, we will be making flying bird kites that you can take outside and use to experiment with the forces of flight. A bird’s feathers are also incredibly strong yet light, reducing the weight required to lift the bird off of the ground. Smaller-winged birds need to flap their wings faster to get the same amount of lift as those with larger wings. The wings provide the force of lift, which is stronger the larger the wing is. For example, birds have hollow bones, strong muscles, a beak instead of a jaw with teeth (much lighter), and a smooth body shape that reduces drag. This means that their bodies have special differences from ours that help them fly. In order for something to fly, whether it be a kite or a bird, its Lift and Thrust must be stronger than its Weight and Drag, kind of like a game of Tug-o-War!īirds are able to overcome the forces of weight and drag when they fly because of special adaptations to their bodies. These forces pull objects down toward the ground (weight) and backward from the direction of flight (drag). The other forces of flight acting on objects are Weight and Drag. Birds get lift and thrust from flapping their wings and taking advantage of wind in a similar way to kites. Kites get lift and thrust from strong winds that help push the kite upward into the sky. Lift is a push upward and Thrust is a push forward. Lift and Thrust are the forces that help flying things get off of the ground. whether man-made like kites or things in nature like birds take off into the air and stay. Forces can help with flight, or make flight more difficult. corner edge of the kite template copied on legal size paper. These forces affect all flying things, including birds and kites! A force is a push or pull acting upon an object. The four forces of flight are weight, lift, drag and thrust. ![]() Shipping to Canada is a flat rate of $14.99 and all other countries are $19.99 and there is also no extra charge when shipping more than one item.Īll orders are shipped promptly using the United States Postal Service.Have you ever wondered how birds are able to fly or why kites soar so high?
