Let's solve the puzzle based on
Newton’s First Law of Motion and fill in the missing words from the sentences. The worksheet explains Newton’s First Law, so we can use that information to complete the blanks.
---
Here are the completed sentences with explanations:
---
1. One example of an outside force that slows down moving objects is
👉
friction
> *Explanation:* Friction is a force that opposes motion. It acts between surfaces in contact (like tires and road, or your body and seat). It slows down moving objects. Other examples include air resistance or braking forces.
---
2. Newton's law says that an object in motion will stay in
👉
motion
> *Explanation:* This is part of Newton’s First Law: "An object in motion tends to stay in motion..." unless acted upon by an external force.
---
3. Newton said that a moving object will travel at a steady
👉
speed
> *Explanation:* Newton’s First Law states that a moving object continues in motion at a constant speed and in a straight line unless acted upon by an outside force.
---
4. Objects stay at rest or in motion until an outside
👉
force
> *Explanation:* The key idea here is that a change in motion (starting, stopping, changing direction) requires an external force. Without it, objects maintain their state of motion.
---
5. When an object is not moving, it is at
👉
rest
> *Explanation:* “At rest” means the object has zero velocity — it's not moving.
---
6. A moving object will go in a
👉
straight
> *Explanation:* According to Newton’s First Law, unless acted upon by a force, a moving object travels in a straight line at constant speed.
---
7. Isaac Newton described how objects behave with his
👉
laws
> *Explanation:* Newton formulated three laws of motion, and this one is called the
First Law of Motion.
---
Another name for Newton’s First Law of Motion is:
👉
The law of inertia
> *Explanation:* Inertia is the tendency of an object to resist changes in its motion. That’s exactly what Newton’s First Law describes — objects resist changes to their state of motion.
---
Final Answer Key:
1.
friction
2.
motion
3.
speed
4.
force
5.
rest
6.
straight
7.
laws
→ Another name:
The law of inertia

Now, if you're supposed to
solve a puzzle using the boxed letters, let's check if there are any letters highlighted or boxed in the original image. Since I can't see the image, but based on typical layouts like this, the
first letter of each answer might be used to form a word.
Let’s extract the
first letter of each answer:
1.
f (friction)
2.
m (motion)
3.
s (speed)
4.
f (force)
5.
r (rest)
6.
s (straight)
7.
l (laws)
That gives:
F M S F R S L — doesn’t make sense.
But wait — maybe it's the
boxed letters in the sentences? For example, sometimes worksheets have letters in boxes next to answers.
Alternatively, perhaps the
last letter or
specific letters are boxed.
But since the image isn't visible, and based on common puzzles like this, the most likely
puzzle solution is:
>
"The law of inertia" — which is the alternative name for Newton’s First Law.
So the final answer to the puzzle is likely:
👉
Inertia
And the sentence:
Another name for Newton’s First Law of Motion is: The law of inertia.
✔ That’s the key concept!

If you have a grid or specific letters boxed, please describe them, and I can help decode the puzzle further. But based on the text provided, this is the correct completion.
