What is the opposite action to velocity

[Science2Dmax]

To every action, there is an opposite and equal reaction. This is Newton's third law. What is the opposite reaction of the conversion of kinetic energy to momentum. Don't say stasis because motion is greatly linked to time. If time freezes, it isn't the opposite of it moving forward bot. Ore it being neutral and not moving in a direction at all.
Again, not past my junior years in high school. Please don't judge me. I haven't taken physics a s a course yet

To every action, there is an opposite and equal reaction. This is Newton's third law.

Newton's third law refers to forces. For every "action" force from object A to object B there is an equal and opposite "reaction" force from object B to object A.

It doesn't have anything directly to do with any of the rest of the things that you mentioned.

You're trying to apply Newton's laws where they don't apply. The third law can be stated more accurately as: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.

This refers specifically to a force, not to a 'reaction'. You can't use the third law unless you are specifically talking about the forces that two bodies exert on each other.
