"forces between molecules"
Newton's third law<span> is: For every </span>action, there is an equal and opposite reaction. This means that in every interaction, there is a<span> pair of forces acting on the two interacting objects.</span>
<span>Matter of all types have gravity, which causes it to attract to each other. The most efficient way for all this matter to congregate is the sphere. As they consolidate, they form the shape. As they compress, temperatures in the center of the mass start to go up and if it hits the proper point, it can ignite and become a star.</span>
True.
There is heat energy, for example, and it doesn't involve motion.
