1. Which two factors affect the average kinetic energy of the particles of any type of matter?
2. What happens to the speed of the particles if the temperature is increased?
3. Click the “Next” button so you can change the mass of the particles. What happens to the speed of the particles if the size of the particle is increased?
4. Click the “Next” button so you can change the mass and temperature of the particles. What do you have to do to give the particles of the matter the most kinetic energy? Do the particles move fast or slow at this point?

1. Mass and Velocity

2.The speed of the particles increases.

Explanation:

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.
