Interactive static electricity worksheet with images and diagrams for learning about attraction, repulsion, and electric charges.

Problem Analysis:

The worksheet is divided into two main sections:
1. Identifying Static Electricity: The first part asks you to identify images that demonstrate static electricity.
2. Determining Attraction, Repulsion, or No Effect: The second part requires you to analyze the interactions between charged objects and determine whether they attract, repel, or have no effect on each other.

Section 1: Identifying Static Electricity

Static electricity occurs when there is an imbalance of electric charges on objects. This can result in phenomena such as attraction, repulsion, or sparks. Let's analyze each image:

#### Image 1:
- Description: A circuit with a battery, wires, and a bulb.
- Analysis: This demonstrates electric current, not static electricity. Static electricity involves stationary charges, whereas this shows moving charges (current).

#### Image 2:
- Description: A comb attracting small pieces of paper.
- Analysis: This is a classic example of static electricity. When a comb is rubbed against hair or fabric, it gains a static charge, which attracts lightweight objects like paper.

#### Image 3:
- Description: A person combing their hair.
- Analysis: This can generate static electricity. Rubbing the comb through hair transfers electrons, creating a static charge on both the comb and hair.

#### Image 4:
- Description: A child holding a balloon, with their hair standing up.
- Analysis: This is another classic example of static electricity. Rubbing a balloon on hair transfers electrons, causing the balloon and hair to become oppositely charged, resulting in attraction.

#### Image 5:
- Description: A circuit with a battery, wires, and a motor.
- Analysis: This demonstrates electric current, not static electricity. It involves moving charges, not stationary ones.

#### Image 6:
- Description: A person experiencing a spark when touching a door handle.
- Analysis: This is a clear example of static electricity. The spark is caused by the discharge of static electricity built up on the person's body.

Images Expressing Static Electricity:

- Image 2 (comb attracting paper)
- Image 3 (combing hair)
- Image 4 (balloon making hair stand up)
- Image 6 (spark from touching a door handle)

Section 2: Determining Attraction, Repulsion, or No Effect

In static electricity, the interaction between charged objects follows these rules:
- Opposite charges attract (e.g., positive and negative).
- Like charges repel (e.g., positive and positive, or negative and negative).
- Neutral objects are unaffected unless influenced by a charged object.

Let’s analyze each pair of objects:

#### Image 7:
- Description: A positively charged balloon near a negatively charged wall.
- Analysis: Opposite charges attract.
- Answer: Attract

#### Image 8:
- Description: Two negatively charged surfaces facing each other.
- Analysis: Like charges repel.
- Answer: Repel

#### Image 9:
- Description: A positively charged surface near a negatively charged surface.
- Analysis: Opposite charges attract.
- Answer: Attract

#### Image 10:
- Description: Two positively charged balloons near each other.
- Analysis: Like charges repel.
- Answer: Repel

#### Image 11:
- Description: A positively charged surface near a negatively charged surface.
- Analysis: Opposite charges attract.
- Answer: Attract

#### Image 12:
- Description: A positively charged shirt near a negatively charged balloon.
- Analysis: Opposite charges attract.
- Answer: Attract
