Gravity is a non-contact force since the two objects don't have to be touching to feel the force of gravity. How can you increase the force of gravity? Select all that apply. decrease the mass of both of the objects 50 points

increase the distance between the objects

decrease the distance between the objects.

increase the mass of one of the objects

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.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
