1. A book resting on a table: The book experiences the force of gravity pulling it downwards, and the force of the table pushing upwards. These forces are equal in magnitude and opposite in direction, resulting in a net force of zero. This keeps the book stationary.

2. A tug-of-war with no movement: Two teams pull on a rope with equal force in opposite directions. The forces balance each other out, and the rope remains motionless.

3. A car traveling at a constant speed on a straight road: The car's engine provides a forward force, while air resistance and friction from the tires oppose the motion. When these forces balance, the car maintains a constant velocity (speed and direction).
