Inertia- An object's tendency to resist a change in motion.

Friction- A force that slows down moving objects.

Mass- Number of atoms or physical matter an object is composed of, measured in kilograms.

Acceleration- The rate of change of velocity of an object, measured in m/s/s.

Reaction force- The force that is equal in strength and opposite in direction to the action force.

Interaction- A mutual action between objects where each object exerts and equal but opposite force on the other.
