In flight the engine thrust must overcome the air resistance, or drag. Drag depends on frontal area (for example, large, airliner; small, fighter plane) and shape (drag coefficient); in level flight, drag equals thrust. The drag is reduced by streamlining the plane, resulting in higher speed and reduced fuel consumption for a given power. Less fuel need be carried for a given distance of travel, so a larger payload (cargo or passengers) can be carried.
rockets are streamlined because it helps them to be aerodynamic.
so that they can slip through the air while flying.
so that the air will just glide past the bird and the air will not block the bird.
It decreases air resistance, meaning they can go faster due to a lack of friction.
to fly (birds) = af (עף) to fly (in an airplane) = tas (טס)
The wind pushes the airplane helping it to stay in the air and fly.
if a bird is to an airplane, then a fish is to a boat answer is "submarine" ..god told me dont ask no question
they both fly and go woosh
Understand that a streamlined body shape achieves a greater speed. A streamlined body shape is one that is narrow at both ends, and broad in the middle. This shape enables the animals to fly faster. Streamlined body shape Just like there is water resistance, there is a force called air resistance that opposes motion in air. When a bird is flying, its streamlined body shape helps to reduce air resistance
Air resistance actually holds an airplane back. It must overcome that resistance to fly.
the same way they help a bird fly
horsefly bird ladybug butterfly fly dragonfly bee frisbee blimp airplane balloon paper airplane hot air balloon kite
in a conventional airplane it connects the wing to the control surfaces in the tail.
It has hollow bones to let it be lighter, streamlined body shape to reduce air resistance and strong muscles to flap their wings.
Because they are streamlined which helps it cut throught he air and move fatser :)
The Wright Brothers were inspired by how birds fly, they studied them and they observed them. They started to discover aerodynamics and how the birds are able to fly, so they made an airplane that was kind of like a bird.
