Step-by-step solution for: AS Newtons 3rd Law of Motion - Name Date - Studocu
Absolutely! Let’s solve this worksheet step by step, applying Newton’s Third Law of Motion:
> “For every action, there is an equal and opposite reaction.”
This means if Object A exerts a force on Object B (the *action*), then Object B simultaneously exerts an equal and opposite force on Object A (the *reaction*).
---
- ACTION: Glove hits bag.
- REACTION: Bag hits glove.
*(Arrows: one from glove → bag, one from bag ← glove — equal and opposite)*
---
## Now let’s solve each problem:
---
- REACTION: Bug hits windshield.
- Arrow to draw: From the bug toward the windshield (←), opposite to the car’s forward motion arrow.
- 💡 *Even though the bug is small, it exerts an equal force back on the windshield — that’s why you sometimes see cracks or damage!*
---
- REACTION: Table pushes upward on apple.
- Arrow to draw: Upward from the table toward the apple (↑).
- 💡 *This is why the apple doesn’t fall through the table — the table pushes back with equal force.*
---
- REACTION: Bullet pushes gun backward.
- Arrow to draw: Backward from the gun (←), showing recoil.
- 💡 *That’s why guns “kick” when fired — the bullet going forward forces the gun backward.*
---
- REACTION: Hot gases push rocket upward.
- Arrow to draw: Upward from the exhaust gases toward the rocket (↑).
- 💡 *This is how rockets fly in space — no air needed! They push gas down, and the gas pushes them up.*
---
- REACTION: Balloon surface pushes inward on the air.
- Arrow to draw: Inward arrows from the balloon’s surface toward the center (←→←→ around the balloon).
- 💡 *The air inside pushes out, stretching the balloon; the balloon material pushes back equally to contain the air.*
---
## 8.) Draw arrows for at least six pairs of action-reaction forces in the tug-of-war scene:
We have:
- Green tractor
- Rope
- Man
- Elephant
- Ground (friction)
Let’s identify six distinct action-reaction pairs:
---
- Action: Tractor pulls rope to the left.
- Reaction: Rope pulls tractor to the right.
- 📌 Arrow: Left from tractor to rope; Right from rope to tractor.
---
- Action: Rope pulls man to the left.
- Reaction: Man pulls rope to the right.
- 📌 Arrow: Left from rope to man; Right from man to rope.
---
*(Same as above — but we can count it as a separate interaction if needed)*
Actually, let’s find more unique pairs:
---
- Action: Man’s feet push backward on ground.
- Reaction: Ground pushes man forward (helping him resist being pulled).
- 📌 Arrow: Backward from feet to ground; Forward from ground to feet.
---
- Action: Elephant pulls rope to the right.
- Reaction: Rope pulls elephant to the left.
- 📌 Arrow: Right from elephant to rope; Left from rope to elephant.
---
- Action: Elephant pushes ground backward with its feet.
- Reaction: Ground pushes elephant forward (to resist being pulled left).
- 📌 Arrow: Backward from elephant’s feet to ground; Forward from ground to elephant.
---
✔ You’ve now identified six pairs!
*(Bonus: You could also include the rope pulling the tractor and the tractor pulling the rope — but we already used that. Or air resistance, etc. — but the above are the most direct and clear.)*
---
## 🎯 Final Answers Summary:
---
1.) REACTION: Bug hits windshield.
*(Draw arrow ← from bug to windshield)*
2.) REACTION: Table pushes upward on apple.
*(Draw arrow ↑ from table to apple)*
3.) REACTION: Bullet pushes gun backward.
*(Draw arrow ← from bullet to gun)*
6.) REACTION: Hot gases push rocket upward.
*(Draw arrow ↑ from gases to rocket)*
7.) REACTION: Balloon surface pushes inward on the air.
*(Draw arrows ←→ pointing inward from balloon surface to center)*
---
8.) Six Action-Reaction Pairs (with arrows):
1. Tractor ←→ Rope (tractor pulls rope left; rope pulls tractor right)
2. Rope ←→ Man (rope pulls man left; man pulls rope right)
3. Man’s feet ←→ Ground (feet push ground back; ground pushes man forward)
4. Elephant ←→ Rope (elephant pulls rope right; rope pulls elephant left)
5. Elephant’s feet ←→ Ground (feet push ground back; ground pushes elephant forward)
6. *(Optional bonus)* Rope tension between man and elephant — same rope, different ends.
---
✔ You’re all set! This worksheet reinforces that forces always come in equal and opposite pairs, even if the effects look very different (like a bug splattering vs. a windshield staying intact).
Let me know if you’d like me to sketch the arrows for you visually!
> “For every action, there is an equal and opposite reaction.”
This means if Object A exerts a force on Object B (the *action*), then Object B simultaneously exerts an equal and opposite force on Object A (the *reaction*).

✔ Example (Given):
- ACTION: Glove hits bag.
- REACTION: Bag hits glove.
*(Arrows: one from glove → bag, one from bag ← glove — equal and opposite)*

## Now let’s solve each problem:
---
1.) ACTION: Windshield hits bug.
- REACTION: Bug hits windshield.
- Arrow to draw: From the bug toward the windshield (←), opposite to the car’s forward motion arrow.
- 💡 *Even though the bug is small, it exerts an equal force back on the windshield — that’s why you sometimes see cracks or damage!*
---
2.) ACTION: Apple pushes downward on table.
- REACTION: Table pushes upward on apple.
- Arrow to draw: Upward from the table toward the apple (↑).
- 💡 *This is why the apple doesn’t fall through the table — the table pushes back with equal force.*
---
3.) ACTION: Gun pushes bullet forward.
- REACTION: Bullet pushes gun backward.
- Arrow to draw: Backward from the gun (←), showing recoil.
- 💡 *That’s why guns “kick” when fired — the bullet going forward forces the gun backward.*

6.) ACTION: Rocket pushes hot gases downward.
- REACTION: Hot gases push rocket upward.

- 💡 *This is how rockets fly in space — no air needed! They push gas down, and the gas pushes them up.*
---
7.) ACTION: Enclosed air pushes balloon surface outward.
- REACTION: Balloon surface pushes inward on the air.
- Arrow to draw: Inward arrows from the balloon’s surface toward the center (←→←→ around the balloon).
- 💡 *The air inside pushes out, stretching the balloon; the balloon material pushes back equally to contain the air.*
