Final answer:
Inertia, friction, and kinetic energy are concepts in physics that relate to object motion and energy.
Step-by-step explanation:
Inertia, friction, and kinetic energy are concepts in physics. Inertia refers to the tendency of an object to resist changes in its motion. Friction is the force that opposes the motion of an object when it comes into contact with another object or surface. Kinetic energy is the energy an object possesses due to its motion.
