Here's why:
* Force: A force is a push or pull that can cause a change in an object's motion.
* Net Force: The net force is the overall force acting on an object, taking into account the direction of all forces. It's the vector sum of all the individual forces.
Key Points:
* A non-zero net force means there's an imbalance of forces acting on the object.
* This imbalance will cause the object to accelerate (change its velocity) in the direction of the net force.
* If the net force is zero, the forces are balanced, and the object will either remain at rest or continue moving at a constant velocity.
