Well, there are several ways to go about answering this.
Inertia is the property of an object at rest resisting motion.
First: Pmomentum is the property of an object in motion to resist change in that motion.
Second: Potential Energy is the property of an object at rest to begin moving, it typically results from height.
Third: Kinetic Energy is the property of an object in motion to keep moving. [here both of our categories are opposite of inertia] This is likely the best bet.
Any of these are good options if your answer is limited to the field of Fizex. (Then again, Quantum physics is fairly different from inertia too.)
Finally: If your answer isn't related to Fizex, Waffles, Historical figures, language, and philosophy are very different from Inertial.
A synonym is momentum, but usually only for moving objects.
Immobile is the opposite of motion. Motionless is also the opposite of motion. When something is motionless, it doesn't have energy moving it.
Inertia.
Since momentum is directional, the opposite of momentum is an opposed momentum, going in the opposite direction.
Friction is the force that is always in opposition to motion. However any force that tends to slow or stop motion, is oppositional to it.
Lubricity
Friction opposes motion so the friction force will be in the direction opposite to that in which the fridge is pushed.
The direction of the force of friction is opposite of the direction of the motion.
Friction always acts opposite to the direction of motion.
Friction acts in the opposite direction of the object's motion
If the speed is constant, then the group of forces acting on the object is balanced. So the portion of the force acting in the direction of the motion must be equal and opposite to the force of friction.
The "force" of friction is always exactly opposite the direction of motion.
there is nothing called as principle of friction. friction is just a force which will act in the opposite direction of which you apply force.
the direction of force of friction provided from earth is in its opposite direction.i.e the wheel and frictional force are both opposite to each other
There is no force opposite to friction. In fact, friction is not actually a force, although we treat it as if it were one, in order to make the math and physics easier. The concept of a force opposite to friction might be 'lubricity' ... the ability of two surfaces to slide past each other. The opposite force of friction depends on all the other forces applied to any moving object, since those determine the object's motion, and friction always acts in the direction exactly opposite to the object's motion.

friction is: When an object exerts an opposite force on an object in motion.

Friction often does that.

Friction opposes motion so the friction force will be in the direction opposite to that in which the fridge is pushed.
The opposite force to friction is momentum. Because friction stops an object from moving or slows an object down, momentum keeps it at speed.
