Project Beak Adaptations Wings Flight Physics of Flight ~ Some birds such as hawks and osprey use warm air currents to soar through the air As the suns energy warms the earths surface warm air is created and rises This uplifting of warm air is known as a thermal Soaring birds use the lift upward force that opposes the pull of gravity from this warm air to soar
How Do Birds Fly Montana Science Partnership ~ Birds use the same laws of physics to fly as any winged craft or creature The wings act as an airfoil When an airfoil moves forward though a fluid all gases are actually “fluids” it creates “lift” The lift on an airfoil is primarily the result of its shape particularly with regards to two aspects of shape
Q A How do birds fly Department of Physics ~ The bird uses its strong muscles to push its wings downwards pushing air downwards generating lift and if the wings are angled properly also thrust The big problem then becomes not pushing air back upwards when the bird moves its wings up for the return stroke
Drinking bird Wikipedia ~ Construction and materials A drinking bird consists of two glass bulbs joined by a glass tube the birds neck The tube extends nearly all the way into the bottom bulb and attaches to the top bulb but does not extend into it The space inside the bird contains a fluid usually colored

Work physics Britannica ~ Work in physics measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement If the force is constant work may be computed by multiplying the length of the path by the component of the force acting along the path
Work physics Wikipedia ~ Work is the product of force and displacement In physics a force is said to do work if when acting there is a movement of the point of application in the direction of the force For example when a ball is held above the ground and then dropped the work done on the ball as it falls is equal to the weight of the ball multiplied by the distance to the ground When the force F displaystyle F is constant and the angle between the force and the displacement s displaystyle s is θ then the
Ancient Physics History of Physics ~ His work in ancient physics spread around the known world and was the major conduit through which the knowledge of the Greeks passed on to the great Islamic scholars of the medieval period
