Educational worksheet on types of motion, including definitions and matching activities for rectilinear, circular, rotational, and periodic motion.

Let's solve the worksheet step by step and explain each part.

---

1) What is this? Match

We are given four images and need to match them with the correct type of motion:

#### Image 1: Clock (analog clock face)
- The hands of the clock move in a repeating pattern over time.
- This is periodic motion because it repeats at regular intervals (e.g., every 12 hours for the hour hand).
✔ Answer: Periodic motion

#### Image 2: Ferris wheel
- The Ferris wheel moves in a circular path.
- Each seat follows a circular path, but the whole structure rotates around a central axis.
- This is circular motion — objects moving along a circular path.
✔ Answer: Circular motion

#### Image 3: Cars on a road
- Cars are moving in a straight line along the road.
- This is rectilinear motion — motion in a straight line.
✔ Answer: Rectilinear motion

#### Image 4: Soccer ball
- A soccer ball can spin or rotate about its own axis when kicked.
- If we're focusing on the spinning of the ball, it's rotational motion — rotation about an internal axis.
✔ Answer: Rotational motion

> ✔ Final Matching:
> - Clock → Periodic motion
> - Ferris wheel → Circular motion
> - Cars → Rectilinear motion
> - Soccer ball → Rotational motion

2) Complete the text

> The motion is _________________________.
> The circular motion is _______________________.

This seems like a general definition task. Based on the definitions provided in the image:

- "The motion is" likely refers to periodic motion since the clock example is periodic.
- But looking at the context, perhaps they want us to define circular motion.

Let’s use the definitions from the top of the page:

> Periodic motion: Objects move in equal periods of time.
> Circular motion: Objects move in a circle line.

So, let's fill in:

> The motion is periodic motion.
> The circular motion is motion in a circular path.

But more accurately, based on the image:

> The motion is periodic motion.
> The circular motion is when objects move in a circular path.

✔ Final Answer:
> The motion is periodic motion.
> The circular motion is when objects move in a circle line.

*(Note: Use exact wording from the image if required.)*

3) Read and choose

Match each scenario with the correct motion type.

#### 1: Ferris wheel / wheel
- A Ferris wheel moves in a circular path.
- But the wheel itself spins around its center — so both circular and rotational apply.
- However, "wheel" implies rotation about an axis.
- So, rotational motion is best for "wheel".
- But Ferris wheel as a ride involves circular motion for passengers.
- Since it says “ferris wheel / wheel”, likely rotational is the intended answer.

✔ Answer: rotational

#### 2: Ball / carousel
- A ball rolling may have rotational motion, but if it's bouncing or spinning, it could be rotational.
- A carousel moves in a circular path — circular motion.
- But also, it repeats every cycle — so periodic motion.
- But the question asks to choose between periodic and circular.
- Carousel = circular motion (it moves in a circle), and it’s also periodic.
- But since only one choice is allowed, and circular is directly visible, better to pick circular.
- But "ball" might refer to a ball on a carousel — so again, circular.

Wait — the phrasing is "ball / carousel", meaning either.

- A ball being thrown in a curved path isn't necessarily circular.
- But if it's a ball on a carousel, it moves in a circle → circular motion.
- Also, carousel is circular and periodic, but circular motion is the primary classification.

✔ Answer: circular

#### 3: Car moving / people walking
- Both move in a straight line (usually).
- This is rectilinear motion.

✔ Answer: rectilinear

#### 4: A clock / planets
- A clock has hands that repeat regularly → periodic motion.
- Planets orbit the sun in circles → circular motion and also periodic.
- But again, the options are rotational and periodic.
- Planets orbit — not rotating about their own axis? Wait: They do rotate, but the motion around the sun is circular and periodic.
- But the option is rotational vs periodic.
- Clocks have periodic motion.
- Planets have periodic orbital motion.
- So both are periodic.

✔ Answer: periodic

✔ Final Answers:

#### 1) Match
- Clock → Periodic motion
- Ferris wheel → Circular motion
- Cars → Rectilinear motion
- Soccer ball → Rotational motion

#### 2) Complete the text
> The motion is periodic motion.
> The circular motion is when objects move in a circle line.

#### 3) Read and choose
1. Ferris wheel / wheel → rotational
2. Ball / carousel → circular
3. Car moving / people walking → rectilinear
4. A clock / planets → periodic
