Here's a breakdown:

* Forces: A push or pull that can cause a change in motion.

* Balanced: Forces are balanced when they are equal in strength and act in opposite directions.

* Cancel each other out: When forces are balanced, they have no net effect on the object they are acting upon.

Example:

Imagine you're pushing a box with a force of 10 Newtons to the right, and your friend is pushing it with a force of 10 Newtons to the left. The box will remain stationary because the forces are equal and opposite.
