Let's solve the problems step by step:
---
Problem 1: When something changes position, it is in:
-
Options: gravity, position, motion, magnetism
Explanation:
When an object changes its position, it means it is moving. The term that describes this change in position is
motion.
Correct Answer:
- Circle the word
motion.

Problem 2: This is an example of:
-
Image: A boy pulling a dog on a leash.
-
Options: push, pull
Explanation:
The boy is using the leash to move the dog toward himself. This action involves applying force to pull the dog. Therefore, this is an example of
pull.
Correct Answer:
- Circle the word
pull.

Problem 3: In this picture, the force is:
-
Image: A girl pushing a door, and the door moves.
-
Options: balanced, unbalanced
Explanation:
Forces are considered
unbalanced when they cause an object to move or change its state of motion. In this case, the girl is applying a force to the door, and the door is moving. This indicates that the forces acting on the door are not equal (i.e., the force applied by the girl is greater than any opposing force), so the forces are
unbalanced.
Correct Answer:
- Circle the word
unbalanced.

Problem 4: Circle the objects that are magnetic:
-
Objects: paperclip, pen, yarn, key
Explanation:
-
Paperclip: Typically made of metal (e.g., steel) and can be magnetic.
-
Pen: Usually contains a metal tip or components, but the body is often plastic and not magnetic.
-
Yarn: Made of wool or synthetic fibers and is not magnetic.
-
Key: Often made of metal (e.g., iron or steel) and can be magnetic.
Magnetic Objects: Paperclip and Key.
Correct Answer:
- Circle the
paperclip and the
key.

Final Answers:
1. Motion
2. Pull
3. Unbalanced
4. Paperclip and Key
Boxed Final Answer:
\[
\boxed{\text{motion, pull, unbalanced, paperclip and key}}
\]
