Answer 2

The concept of balanced and unbalanced forces is a fundamental principle in physics. 1. Balanced forces are those that result in a net force of zero. This means that the object will not change its state of motion, i.e., if it is at rest, it will remain at rest, and if it is moving, it will continue to move at a constant velocity.2. Unbalanced forces, on the other hand, result in a net force that is not zero. This means that the object will change its state of motion, i.e., it will either start moving, stop moving, or change its speed or direction of motion.Let's apply these principles to the given scenarios:A. A tug-of-war match where neither team is moving: The two teams are exerting equal and opposite forces on the rope. Since the net force is zero, this is a balanced force.B. A bicycle rider comes to a stop: The bicycle rider was initially in motion and comes to a stop, indicating a change in motion. This suggests that an unbalanced force (like friction) is acting on the rider.C. A truck is using cruise control: If the truck is moving at a constant velocity, the forces acting on it are balanced. The force of the engine is equal and opposite to the forces of friction and air resistance.D. A tree is knocked down by strong winds: The tree changes its state of motion from rest to motion, indicating that an unbalanced force (the wind) is acting on it.E. A person sitting on a chair: The person is at rest, and the downward force of gravity is balanced by the upward force of the chair (normal force). This is a balanced force.#
