Xander claims that since the model of the atom has been changed so many times, that means it is a weak model. Willow claims that the more a model has been examined and adjusted, the stronger it is. Who is correct and why?

Willow is correct because as things age and mature more, usually the more better they are.

Explanation:

To elaborate, you can perceive the development of the modern day atomic model as one aging and maturing. There's usually a correlation between age/maturity and knowledge, the same is true for the atomic model and other scientific theories.

the answer is yes

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
