* Balanced forces mean no acceleration. When forces are balanced, they cancel each other out, resulting in a net force of zero. Newton's second law of motion states that acceleration is directly proportional to the net force acting on an object. Therefore, with zero net force, there is no acceleration.
* Constant velocity. If an object is not accelerating, it means its velocity is constant. This means the object can be moving at a constant speed in a straight line (constant velocity) even with balanced forces acting upon it.
Examples:
* A car moving at a constant speed on a straight road. The forces of the engine pushing forward and the friction of the tires on the road and air resistance are balanced.
* A skydiver reaching terminal velocity. The force of gravity pulling the skydiver down is balanced by the force of air resistance pushing upward.
* An object floating in water. The force of gravity pulling the object down is balanced by the buoyant force pushing it up.
Key takeaway: Balanced forces do not mean an object is stationary. They mean the object's velocity is constant, whether that's a constant speed or a constant zero speed (i.e., being at rest).
