Question: 1-8 U-Science-Gr6-Unit3-PBT-CBT (2020-21)
Spring 1 and Spring 2 are the same type of spring. Both springs were pushed or compressed into different positions and clamped into place.
Which spring has less potential energy?
O Spring 1
o Spring 2
O Spring 1 & Spring 2 have the same amount of energy.
You cannot tell unless you know what the springs are made of.

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.
