In-text Questions

Answer: If an object is acted upon by balanced forces, its state of motion does not change. If it is at rest, it remains at rest. If it is in motion, it continues to move with a constant velocity (constant speed in a straight line).

- Balanced forces are forces that are equal in magnitude and opposite in direction, acting on an object.
- When balanced forces act on an object, the net force acting on the object is zero.
- According to Newton's First Law of Motion, if the net external force on an object is zero, its acceleration is zero.
- Therefore, if the object is initially at rest, it will remain at rest.
- If the object is initially in motion, it will continue to move with a constant velocity (constant speed in a straight line).
