Let’s go through each question one by one and think carefully about the right answer.
---
Question 1: What is a PUSH or PULL of an object?
We know from science that when you push or pull something, you’re applying a
force.
- Friction is a force that slows things down — not the same as any push/pull.
- Gravity is a specific kind of pull (from Earth), but not all pushes/pulls are gravity.
- Motion is what happens *because* of a force — it’s not the push or pull itself.
✔ So the best answer is
Force.

Question 2: Why is it harder for the boy in Image B to get down the hill?
Image A shows a skier on snow — smooth surface, low friction.
Image B shows a boy walking on grass — rougher surface, more friction.
Friction resists motion, so more friction = harder to move.
Motion, displacement, and work don’t explain why it’s *harder* — they describe movement or energy, not resistance.
✔ So the correct answer is
Friction.

Question 3: If these boys are pulling with the same amount of force. What will happen?
This is a tug-of-war. If both pull with equal force in opposite directions, the forces cancel out.
That means no net force → no movement.
They won’t fall unless one slips — but the question says “same amount of force,” so we assume balanced forces.
No one wins if forces are equal.
✔ So the correct answer is
They will not move at all.

Question 4: It takes more force to accelerate the iron man on the left than the iron man on the right because the iron man on the left has more mass. This best describes...
This is talking about how force, mass, and acceleration are related.
Newton’s Second Law says:
Force = mass × acceleration
So if mass is bigger, you need more force to get the same acceleration.
That’s exactly what this situation shows.
- Universal gravitation? That’s about attraction between masses — not relevant here.
- First law? That’s about inertia — objects staying still or moving unless forced. Not quite.
- Third law? Action-reaction pairs — also not matching.
- Second law? Yes — directly matches F = m × a.
✔ So the correct answer is
Newton's second law, the law of acceleration.

Question 5: The formula ? = mass x acceleration
This is just asking what goes in the blank.
From Newton’s Second Law:
Force = mass × acceleration
So the missing word is
Force.
*(Note: Even though the image cuts off, the pattern is clear — this is continuing Question 4’s concept.)*
✔ So the correct answer is
Force.
