Question

WHEN A PLANE TAKES OFF,WORK IS SAID TO BE DONE. WHY?​

Answer 1

Answer:

This is because energy is required to move the plane and lift it up in the air. So, the work done is converted into the energy of the plane due to which it flies.

Answer 2

we know that,

work is said be done when a force is acting on an object and it displaces it to some distance.

so, in this situation, work is said to be done, because a force is exerted on a plane and it displaces it to a long distance.
