What is the relationship between energy, as measured in joules, and momentum, as measured in kgm/s?

The relationship between energy (measured in joules) and momentum (measured in kgm/s) is that they are both important physical quantities in the study of motion. Energy can be transferred between objects to change their momentum, and momentum can be used to calculate the amount of energy involved in a collision or interaction. In simple terms, energy and momentum are related in the context of how objects move and interact with each other.
