Ostriches don't fly, they run at speeds of 40 MPH. The wings aren't useful, they do help with balance when it's running and needs to change directions.

Why do boomerangs fly?
When thrown the top wing of the spin moves in the same direction ,while the wing on the bottom of the spin moves in the opposite direction of the throw. The wing on top is spinning at the same speed as the bottom wing. More air passes under the top wing which lifts the boomerang. The boomerang travels in a circle returning back to the thrower.
Whats the relationship between speed and lift?
Lift is proportional to the density of the air and approximately proportional to the square of the flow speed. Lift also depends on the size of the wing, being generally proportional to the wing's area projected in the lift direction.
What part of the planes wing controls the direction of the plane?
Rudder on the wing of the plane controls the direction.
What are facts about ostriches?
Ostriches are unable to fly but their bodies are built for running. In fact, they can maintain a speed of 30 miles per hour.
What is speed is given direction?
The amount of speed in a given direction is the 'component' of speed in that direction. The total amount of speed AND the direction of the total speed is the 'velocity' of the moving object.
If ostriches are birds why can't they fly?
Ostriches are flightless birds, most of which are classified as "ratites." These include the rhea, emu, cassowary and kiwi. They have flat breastbones (no anchor points for large wing muscles) and the concurrent shorter wings.
Why speed doesn't have direction?
speed does have direction :p
What is speed in a given direction is called?
Speed in a given direction is velocity.
What is speed in given direction?
The amount of speed in a given direction is the 'component' of speed in that direction. The total amount of speed AND the direction of the total speed is the 'velocity' of the moving object.
You want to design a hand glider wing can you say what is the variables you should take into account of?
The length of the wing, the weight of the wing, and the angles of the wing have impact. So do the speed thrown, wind speed, and temperature.
Speed of an object in a paticular direction?
Speed =distance/time Speed in a particular direction become velocity, a vector, which has magnitude and direction.
Velocity is the change of speed and direction of an object?
No. Velocity is the present speed and direction of motion.If speed or direction changes, then that's 'acceleration'.
