HOW DO PLANES FLY????!!!!!!!!!

HELLO GUYS.

we all have seen so many types of planes during fly in the sky and also we all know very well about gravity force that apply on every object on the earth.so guys whenever we see an aeroplane in the sky so we always think that how can it flies????,why does not gravity apply on it????,why does not plane fall down ??????

SO GUYS TODAY I AM GOING TO TELL YOU ANSWERES OF YUR ALL QUESTIONS:-

in actually guys,there are four forces keep an plane in the sky.they are lift,thrust,weight(gravity) and drag.

lift:-it pushes the plane up and the way air moves around the wings gives the aeroplane lift.the shapes of wings help with lift too.

weight:-it is the force that pulls the plane toward earth,plane are built so that their weight is spread from front to back.this keeps the plane balanced.

thrust:-it is the force that moves the plane forward.engines give thrust to airplane.sometimes an engine turns a propeller.sometimes it is a jet engine,it doesn't matter as long as air keeps going over the wings.

drag:-drag slows the plane . you can feel drag when you walk against the strong wind.planes are designed to let air pass around them with less drag.

so, in a simple way an airplane flies when all four forces work together.and most planes need one more thing that is'pilot'.don't forget pilot because we know mostly without pilot an aeroplane can't fly .

SO GUYS BECAUSE OF THAT FORCES ALL PLANES FLY AND THAT IS WHY THEY DON'T FALL DOWN ON EARTH AND THEY KEEP IN THE SKY.
