Light propeller driven aircraft can take off as low as 50 mph. Basically the heavier an aircraft is, the higher speed it takes off. - A fully laden 747 will take off at approximately 170 mph.
There is not much point in having airplanes unless they 'take off' .
Window shades have to be open for takeoff on airplanes for safety reasons. In case of an emergency, having the shades open allows passengers and crew to see outside and assess the situation, which can be crucial for evacuation or emergency response.
Airplanes need to generate lift in order to take off and fly. The way they do this is to go fast enough on the ground so that the air passing over the wings generates lift in accordance with Bernoulli's principle. When sufficient speed is attained to generate the necessary lift, the plane will fly.
No. Not always. For many airplanes, it may be required if the airplane is fullly loaded.
It is called a runway, and it is also referred to as the tarmac, which is what the runway is made out of.
Airplanes need a lot of speed to take off because they are not designed for vertical takeoff and are to heavy to do so.
100-280 kph.
Yes, airplanes rely on friction during takeoff and landing. Friction between the aircraft's wheels and the runway helps it accelerate for takeoff and decelerate upon landing. Additionally, control surfaces like ailerons and flaps also use friction to adjust the aircraft's direction and speed in flight.

Climb out is the phase of flight which begins immediately after takeoff and continues until the airplane levels off at its cruising altitude.
Airplanes are made for fast transposrt of passengers or cargo. They are also used for defence purposes.
