What is the incorrect belief regarding an object's motion under an unbalanced force?
What is the incorrect belief regarding an object's motion under an unbalanced force?
- An object will stop moving when an unbalanced force is applied. (correct)
- An object maintains its motion without any force acting upon it.
- An object changes its motion proportionally to the unbalanced force applied.
- An object will continue moving in a straight line at a constant speed.
Which statement correctly describes the effect of an unbalanced force on an object's motion?
Which statement correctly describes the effect of an unbalanced force on an object's motion?
- An unbalanced force has no effect on an object's acceleration.
- An unbalanced force can only change the direction of motion.
- An unbalanced force can alter both the speed and direction of motion. (correct)
- An unbalanced force cannot change an object's speed.
What does it mean for an object to move with uniform motion?
What does it mean for an object to move with uniform motion?
- The object experiences a decrease in speed continuously.
- The object accelerates in the direction of the applied force.
- The object moves while experiencing balanced forces only.
- The object maintains a constant velocity without changing direction. (correct)

Study Notes
Unbalanced Forces and Motion
- A common misconception about the relationship between motion and unbalanced forces is that an unbalanced force is required for an object's motion to continue. This is incorrect!
- An unbalanced force causes a change in an object's velocity, either in speed, direction, or both.
- An object will maintain a constant velocity when the net force acting on it is zero.
- The effect of an unbalanced force on an object's motion is described by Newton's Second Law of Motion.
- An unbalanced force on an object directly relates to the object's acceleration, with greater forces producing a higher acceleration.
- An object moving with uniform motion implies a constant velocity.
- This means that its speed and direction do not change.
- It's essential to remember that an object can maintain uniform motion even when acted upon by balanced forces.
- Balanced forces result in no net force, thus allowing the object to continue moving with constant velocity.
