boats and aeroplanes are given special shapes inorder to reduce the loss of energy in overcoming friction
Because they can float and fly easily.
Streamlined shapes make them faster and more fuel-efficient.
a wings on top must be in curved shape and same on bottom also
They have streamlined bodies so that they can cut through the wind and air
yes there will, actually i don't think the shape and principles of flying will change that much
The shape of a Frisbee is a disc, with an airfoil cross-section. As with aeroplanes, this airfoil shape generates lift as it moves through the air.
Iron is heavier than aluminium. Aluminium is easier to form, shape and machine.
Any 4 sided shape is a quadrilateral. If all sides are of different lengths, that is as specific as you can get. Other 4 sided shapes have special characteristics about them, so they are given special names. They are still quadrailaterals.
triangle
The sum of all the sides of a given shape is the perimeter of that shape.
The body of ships and boats are streamlined coz that they can experince minimum amount of Friction while moving through water
no
