What does it mean if data are reproducible but not accurate? the data can be produced over and over but are not close to the accepted value. the data are close to the accepted value but cannot be produced over and over. the data are close to the accepted value and are close to one another. the data are close to the accepted value but are not close to one another.

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.

not too sure thinking all accelerations are pointed down
