The moon orbiting Earth
Explanation:
- The work done is given by:
W = integral (F).ds
In words, It is the dot product of Force in the change displacement. In every case the the force is in the direction of displacement.
Except, when the moon is orbiting the earth, the change in displacement is zero. Hence, the work done is zero as ds = 0.

Physics is important in our daily life because it deals with daily objects we need like light, electricty and sound. Without physics, we cant have the ability to see because lights wont be a thing, we cant use phones, cars and such because they wont work without electricty, you wont be able to listen to your favourite band without sound!
