Here's why:
* Newton's First Law of Motion (Inertia): 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.
* Net Force: The net force is the overall force acting on an object after considering all forces and their directions.
* Balanced Forces: When forces are balanced, the net force is zero. This means the forces cancel each other out.
Example:
Imagine a box sitting on a table.
* Gravity pulls the box downwards.
* The table's normal force pushes the box upwards.
These forces are equal in magnitude and opposite in direction, making the net force zero. As a result, the box remains at rest.
Key takeaway: An object can be at rest even with forces acting upon it if those forces are balanced, resulting in a net force of zero.
