Let's go through each question in the worksheet
"Forces and Interactions: Assessment 1" and solve it step by step with explanations.
---
1. When something changes position it is in:
Options:
- gravity
- position
- motion
- magnetism
✔ Correct answer: motion
Explanation:
When an object changes its position over time, it is said to be in
motion. Motion refers to the change in position of an object relative to a reference point. Gravity and magnetism are types of forces, not states of movement. "Position" is just a location — changing it means motion has occurred.
👉 So, check the box next to
motion.

2. This is an example of...
(Image shows a boy walking a dog on a leash.)
Options:
- push
- pull
✔ Correct answer: pull
Explanation:
The boy is holding the leash, and the dog is pulling forward. The force applied by the dog (or the person) via the leash is a
pull because the dog is being pulled toward the person, or vice versa. A
push would involve pushing something away (like shoving a door).
👉 So, check the box next to
pull.

3. In this picture, the force is...
(Image shows a girl pushing a door, which moves.)
Options:
- balanced
- unbalanced
✔ Correct answer: unbalanced
Explanation:
When the door moves, it means there is a
net force acting on it — that is, the forces are
unbalanced. If forces were balanced, the door would stay still (no motion). Since the girl applies a force and the door moves, the forces are unbalanced.
👉 So, check the box next to
unbalanced.

4. Circle the objects that are magnetic.
Objects shown:
- Paperclip
- Pen
- Ball of yarn
- Key
✔ Magnetic objects:
-
Paperclip – typically made of steel (iron), so it is magnetic.
-
Key – usually made of metal like iron or steel, so it is magnetic.
✘ Not magnetic:
-
Pen – most pens have plastic bodies and non-magnetic ink; even if it has metal parts, they're usually not magnetic.
-
Ball of yarn – made of fabric or wool, not magnetic.
👉 So,
circle the paperclip and the key.
---
✔ Final Answers:
1.
motion
2.
pull
3.
unbalanced
4.
Circle the paperclip and the key
