A ball being dropped from a building What is the relationship between the ball's kinetic energy and potential energies as it falls?

Potential energy is transformed into kinetic energy

Explanation:

I think the option b is the correct answer because as the ball is throwed the potential energy is changed into kinetic energy

true tan speed = ang vel x radius

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.
