Is opening of door an example of a moment of force? investigate

No, opening of door is not an example of a moment of force.

Explanation:

Because moment of force means; tendency to cause a body to rotate about a specific point or axis.

And it's different from the tendency for a body to move, or translate, in the direction of the force.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
