The force of attraction between objects that is due to their masses

I am 100% sure that this answer is gonna be Gravity because the distance and mass are the two things that can differ the "force" of one thing...Gravity.

Explanation:

where is the diagram?

if you insert the diagram ill be able to you

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
