What is the difference between output and input forces

Output Force- the force exerted on an object by a simple machine

Input Force-  the initial force used to get a machine to begin working.

Input Force represents the amount of force that you put into another object. Output Force represents the force that a specific object has as a result of the input force.

- Hope this Helps :)

the force on the thing and the distance the force moves the thing

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.
