* Velocity: Velocity describes both an object's speed and direction.
* Force: A force is a push or pull that can change an object's motion.
* Balanced Forces: When forces acting on an object are balanced, they cancel each other out. This means the net force (the overall force acting on the object) is zero.
Examples of Balanced Forces:
* An object at rest: Imagine a book sitting on a table. The force of gravity pulling the book down is balanced by the normal force from the table pushing the book up.
* An object moving at a constant speed and direction: A car driving at a steady 50 mph on a straight road has balanced forces. The engine's forward force is balanced by air resistance and friction from the tires.
Key Points:
* No acceleration: Balanced forces mean there is no net force, and therefore no acceleration. Acceleration is a change in velocity (either speed or direction).
* State of motion: An object with balanced forces will either remain at rest or continue moving at a constant velocity. This is Newton's First Law of Motion (Law of Inertia).
