Newtons Laws of Motion Worksheet - Free Printable

Let’s go through each question one by one. We’re matching statements to Newton’s Laws of Motion — or choosing “None” if the statement is a misconception or not directly tied to any law.

---

Question 1:
*The more mass an object has, the more force required to accelerate the object.*
→ This is exactly what Newton’s 2nd Law says: F = m × a. More mass → more force needed for same acceleration.
✔ Answer: B. 2nd Law

---

Question 2:
*What goes up, eventually must go down.*
→ This sounds like gravity pulling things back, but it’s NOT one of Newton’s laws. It’s just how gravity works on Earth — objects fall because of gravitational force, not because of a specific law about “going up and down.” Also, in space, things don’t necessarily come down! So this is a generalization/misconception.
✔ Answer: D. None

---

Question 3:
*Eventually all objects at rest will be put into motion.*
→ No! Newton’s 1st Law says objects at rest stay at rest unless acted on by a force. They don’t *eventually* move on their own. This is a misconception.
✔ Answer: D. None

---

Question 4:
*The acceleration experienced by an object is proportional to the force causing the acceleration and inversely proportional to the mass of the object.*
→ That’s the exact wording of Newton’s 2nd Law: a = F/m.
✔ Answer: B. 2nd Law

---

Question 5:
*If two objects interact, the force exerted by one object is equal to and opposite the force exerted by the other object.*
→ That’s Newton’s 3rd Law: For every action, there’s an equal and opposite reaction.
✔ Answer: C. 3rd Law

---

Question 6:
*An object in motion wants to keep moving in a straight line at a constant velocity.*
→ That’s Newton’s 1st Law (Law of Inertia). Objects keep doing what they’re doing unless forced to change.
✔ Answer: A. 1st Law

---

Question 7:
*Objects affected by unbalanced external forces will have a change in its original state of motion.*
→ Yes! Unbalanced forces cause acceleration — that’s Newton’s 2nd Law. Also connects to 1st Law (which says balanced forces = no change). But since it mentions “change in motion,” it’s pointing to 2nd Law.
✔ Answer: B. 2nd Law

---

Question 8:
*Eventually all objects in motion will come to a rest.*
→ Nope! Again, Newton’s 1st Law says objects in motion stay in motion unless acted on by a force. On Earth, friction slows them down — but that’s not because they “eventually stop on their own.” This is a common misconception.
✔ Answer: D. None

---

Question 9:
*You have two magnets. You place the south pole of one magnet near the north pole of the other magnet. The magnets quickly move toward each other.*
→ This is magnetic attraction — not described by Newton’s Laws of Motion. Newton’s laws are about forces and motion in general, but this is specifically about magnetism. Also, while Newton’s 3rd Law applies to the forces between them (equal and opposite), the *reason* they move is due to magnetic force, which isn’t covered by Newton’s laws themselves. So best answer is “None” — it’s not illustrating a Newton’s Law directly.
✔ Answer: D. None
