some examples are sand dunes,mudslides,or earthquakes.
That's because forces will ONLY balance under very specific circumstances.
balance
Some examples of natural forces include gravity, friction, air resistance, electromagnetism, and nuclear forces. These forces play a key role in various natural phenomena and processes in the universe.
Force on accelarating object.
Examples of contact forces include friction, normal force, tension, and applied force. These forces require physical contact between two objects for them to act upon each other.
Forces, velocities, accelerations.

External forces are when a force is between something outside and inside the system. Air resistance, cars moving on the road, friction, and gravity are examples of external forces.
