* Equal Magnitude: They have the same strength or size.
* Opposite Direction: They act in directly opposite directions along the same line of action.
Example:
Imagine pushing a box with a force of 10 Newtons to the right. If someone else pushes the box with a force of 10 Newtons to the left, these forces will cancel each other out. The box will remain stationary.
Key Concept:
This concept is explained by Newton's First Law of Motion (Law of Inertia), which states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net force.
In summary, the size of two forces that cancel each other out is the same, and their directions are opposite.
