You are given a sentence and your task is to generate another sentence that supports the given input.

Input: Consider Input: As the centripetal force acts upon an object moving in a circle at constant speed, the force always acts inward as the velocity of the object is directed tangent to the circle.

Output: Centripetal forces cause objects to turn around continuously in a circle.


Input: Consider Input: 14C and 12C are both isotopes of carbon (they each have six protons -- the atomic number is the same), but they have a different number of neutrons (thus the atomic weight is different).

Output: All carbon atoms have six protons.


Input: Consider Input: An atom that gains electrons would be a negative ion.


Output: Atoms that have gained electrons and become negatively charged are called negative ions.
