Educational worksheet for sorting objects by motion types: straight, back and forth, and circular.

Problem Overview:

The task is to classify the given images into three categories of motion: Straight Motion, Back and Forth Motion, and Circular Motion. The goal is to sort the images based on how the objects move.

Key Definitions:

1. Straight Motion: Movement in a straight line.
2. Back and Forth Motion: Movement that alternates between two points (oscillatory motion).
3. Circular Motion: Movement in a circular path.

Images Provided:

Here are the images with descriptions for clarity:
1. Rocking chair
2. Spinning top
3. Clock tower (pendulum)
4. Merry-go-round
5. Golf club swinging
6. Child on a swing
7. Globe spinning
8. Train moving on tracks
9. Person running
10. Car wheel spinning
11. Seesaw
12. Baseball

Solution:

We will analyze each image and categorize it based on its motion type.

#### 1. Rocking Chair
- Motion: Back and forth (oscillates between two points).
- Category: Back and Forth Motion

#### 2. Spinning Top
- Motion: Rotates in a circular path around its axis.
- Category: Circular Motion

#### 3. Clock Tower (Pendulum)
- Motion: Pendulum swings back and forth.
- Category: Back and Forth Motion

#### 4. Merry-Go-Round
- Motion: Rotates in a circular path.
- Category: Circular Motion

#### 5. Golf Club Swinging
- Motion: Moves in an arc (partially circular but not complete rotation).
- Category: Circular Motion

#### 6. Child on a Swing
- Motion: Moves back and forth.
- Category: Back and Forth Motion

#### 7. Globe Spinning
- Motion: Rotates in a circular path.
- Category: Circular Motion

#### 8. Train Moving on Tracks
- Motion: Moves in a straight line along the tracks.
- Category: Straight Motion

#### 9. Person Running
- Motion: Moves in a straight line.
- Category: Straight Motion

#### 10. Car Wheel Spinning
- Motion: Rotates in a circular path.
- Category: Circular Motion

#### 11. Seesaw
- Motion: Moves up and down in a back-and-forth manner.
- Category: Back and Forth Motion

#### 12. Baseball
- Motion: Typically moves in a parabolic trajectory (straight line when thrown), but here we consider its general movement as straight.
- Category: Straight Motion

Final Classification:

- Straight Motion:
- Train moving on tracks
- Person running
- Baseball

- Back and Forth Motion:
- Rocking chair
- Clock tower (pendulum)
- Child on a swing
- Seesaw

- Circular Motion:
- Spinning top
- Merry-go-round
- Golf club swinging
- Globe spinning
- Car wheel spinning
