To answer the question based on Newton's laws of motion, let's analyze each statement:

1. **Statement A: If an object is accelerating, it must be experiencing a nonzero \(\Sigma \vec{F}\).**
   - **True.** According to Newton's Second Law (\( \Sigma \vec{F} = m \vec{a} \)), if an object is accelerating (\(\vec{a} \neq 0\)), there must be a net force acting on it (\(\Sigma \vec{F} \neq 0\)).

2. **Statement B: If an object is remaining at rest, it must be experiencing zero \(\Sigma \vec{F}\).**
   - **True.** If an object is at rest and remains at rest, it is not accelerating, which means the net force on the object must be zero (\(\Sigma \vec{F} = 0\)). This aligns with Newton's First Law of Inertia.

3. **Statement C: If an object is moving, it must be experiencing a nonzero \(\Sigma \vec{F}\).**
   - **False.** An object can move at a constant velocity without any net force acting on it. If there is no acceleration (\(\vec{a} = 0\)), the net force is zero (\(\Sigma \vec{F} = 0\)), even though the object is still in motion (Newton's First Law).

### Correct answers: **A and B.**

Here are 5 follow-up questions for deeper understanding:
1. What happens to an object when \(\Sigma \vec{F} = 0\) but the object is moving?
2. How does Newton's Second Law describe the relationship between force, mass, and acceleration?
3. Can you provide an example where an object is moving but \(\Sigma \vec{F} = 0\)?
4. What is the significance of Newton's First Law of Inertia in understanding motion at rest?
5. How would you determine the net force on an object if you know its mass and acceleration?

### Tip:
Always remember: net force causes changes in motion (acceleration), but motion itself can occur even without a net force if the object is moving at constant velocity.

Which of these statements are true? Choose all answers that apply: A. If an object is accelerating, it must be experiencing a nonzero ΣF. B. If an object is remaining at rest, it must be experiencing zero ΣF. C. If an object is moving, it must be experiencing a nonzero ΣF.

Analyze true and false statements regarding net force and motion based on Newton's laws of motion. Learn which conditions imply zero or nonzero net force. Suitable for high school students studying physics.
