The moon travels in a nearly circular path around earth. if somehow gravitation between earth and moon disappeared, how would the moon's path differ?

moon must follow a movement tangential to the circle at the point where the force disappears

Explanation:

The gravitational force is the attraction due to the mass of the bodies, if this force disappears the centripetal acceleration between the moon and the Earth would disappear and using the first Newton law, every body remains in uniform motion until an external force changes this movement

Consequently, the moon must follow a movement tangential to the circle at the point where the force disappears

in physics zero. in muscle fatigue could be high

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
