Force - Gravity And Newtons 3 Laws Worksheet - Free Printable

Let’s go step by step to match each definition on the left with the correct term on the right.

We’ll read each numbered item and find its best match from A–P.

---

1. Strength or energy as an attribute of physical action or movement.
→ This is describing Force. Force is what causes motion or change in motion.
✔ Match: G. Force

---

2. A coherent typically large body of matter with no definite shape.
→ Wait — this sounds like it might be misworded. “No definite shape” usually describes a liquid or gas, but “coherent large body of matter” could mean something else? Actually, looking at context — this may be trying to say “a large body of matter that has mass” — which would be mass? But let’s check others.

Actually, re-reading: “A coherent typically large body of matter with no definite shape.” That doesn’t fit any standard physics term well. Maybe it’s a typo? Perhaps meant “with definite mass”? Or maybe it’s referring to matter itself? But “matter” isn’t listed.

Wait — look at option O. mass — mass is a property, not a “body”. Hmm.

Alternatively, perhaps this is poorly worded and should be “a body of matter that has mass” → still not helping.

Let’s skip and come back.

Actually — looking again: maybe it’s supposed to be “a body of matter that has weight”? No.

Wait — perhaps it’s “mass”? Because mass is the amount of matter in an object. And “coherent large body of matter” = an object with mass.

But let’s compare to #3.

---

3. A unit or system of units used for expressing how much and object matter weights.
→ This is clearly about weight, because weight is measured in units (like Newtons or pounds). Weight depends on gravity.
✔ Match: P. Weight

So if #3 is Weight, then #2 can’t be weight.

Back to #2: “A coherent typically large body of matter with no definite shape.” — This is confusing. In physics, we don’t have a term for “large body of matter with no definite shape” unless it’s fluid — but fluids aren’t listed.

Wait — maybe it’s a mistake and it should be “with definite mass”? Then it would be mass.

Or perhaps it’s “matter” — but not listed.

Another idea: maybe it’s “inertia”? No, inertia is tendency to resist change.

Let’s look ahead.

Actually — I think there’s a typo in the question. Probably meant: “A measure of the amount of matter in an object” → that’s mass.

And since #3 is about *units* for weight, #2 is likely mass.

✔ Let’s tentatively assign: 2 → O. mass

---

4. The force that attracts a body toward the center of the earth.
→ That’s gravity — specifically Earth’s gravity.
✔ Match: E. Gravity

---

5. The universe using a force that is directly proportional to the product of their masses.
→ This is Newton’s Law of Universal Gravitation: F = G*(m1*m2)/r²
✔ Match: C. Law of Universal gravitation

---

6. An object at rest stays at rest and an object in motion stays in motion.
→ This is Newton’s First Law — also called the law of inertia.
✔ Match: N. Newton's 1st law of motion

(Note: M is Inertia — which is the property, N is the law.)

---

7. A net force is directly proportional to the magnitude of the net force.
Wait — that sentence is circular. Probably typo. Should be: “Acceleration is directly proportional to the net force” — that’s Newton’s Second Law: F=ma.

Looking at wording: “A net force is directly proportional to the magnitude of the net force.” — That makes no sense.

Probably meant: “The acceleration of an object is directly proportional to the net force acting on it.”

That’s Newton’s 2nd Law.

✔ Match: H. Newton's 2nd law of motion

---

8. For every action there is an equal and opposite reaction.
→ Newton’s Third Law.
✔ Match: L. Newton's 3rd law of motion

---

9. A tendency to do nothing or to remain unchanged.
→ That’s inertia — the resistance to change in motion.
✔ Match: M. Inertia

---

10. The resistance that one surface of object encounters when moving over another.
→ That’s friction in general.
✔ Match: D. Friction

---

11. Is the friction that exists between a stationary object and the surface on which it's resting.
→ Static friction — prevents motion from starting.
✔ Match: A. Static friction

---

12. A type of friction motion between two surfaces in contact.
→ This is vague. Could be sliding friction? Rolling? Sliding is common.

Look at options: K is Sliding friction, B is Rolling friction.

“Motion between two surfaces in contact” — if they’re sliding past each other, it’s sliding friction.

✔ Likely: K. Sliding friction

(Unless specified as rolling, default is sliding.)

---

13. Is the force resisting the motion when body (such as a ball and wheel).
→ Ball and wheel suggest rolling — so rolling friction.
✔ Match: B. Rolling friction

---

14. Is a force that is caused by air.
→ Air resistance.
✔ Match: J. Air resistance

---

15. Is defined as the sum of all the forces acting on an object.
→ Net force.
✔ Match: F. Net force

---

16. The velocity at which a falling object moves through a medium such as air.
→ Terminal velocity — when air resistance equals gravity, speed becomes constant.
✔ Match: I. Terminal velocity

---

Now let’s double-check #2.

We assigned #2 → O. mass

Definition: “A coherent typically large body of matter with no definite shape.”

This is still odd. Mass is not a “body”, it’s a property.

Perhaps it’s a misprint and should be: “The amount of matter in an object” → mass.

Given that all other matches are solid, and O is only left for #2, and P is taken by #3, we’ll keep it.

Also, note: Option O is “mass”, and #3 is “unit... for expressing how much... object weighs” → that’s weight, which is correct.

So yes, #2 must be mass — even if wording is bad.

Final matching:

1 → G
2 → O
3 → P
4 → E
5 → C
6 → N
7 → H
8 → L
9 → M
10 → D
11 → A
12 → K
13 → B
14 → J
15 → F
16 → I

All letters used except: S? Wait, options go to P — 16 items, 16 options? Let’s count options:

A to P is 16 options: A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P → yes, 16.

We used all.

List:

1-G, 2-O, 3-P, 4-E, 5-C, 6-N, 7-H, 8-L, 9-M, 10-D, 11-A, 12-K, 13-B, 14-J, 15-F, 16-I

Perfect.
