Gravity And Friction 1 Worksheet - Free Printable

Let's solve this Grade 3 Science Worksheet titled *"Gravity and Friction"*. The task is to draw and label one arrow for the pull of gravity (which always acts downward toward the center of the Earth) and one arrow for the force of friction (which opposes motion and acts in the opposite direction of movement or intended motion).

---

🔍 Understanding the Forces:

- Gravity: Always pulls downward, toward the Earth. It acts on all objects with mass.
- Friction: A force that opposes motion. It acts parallel to the surface and in the opposite direction of motion (or attempted motion).

---

Now, let’s go through each situation and explain where to draw the arrows:

---

1. Putting on the brakes to stop a bicycle

- Gravity: Draw an arrow pointing straight down from the bike or rider. Label it: Gravity.
- Friction: When braking, the tires grip the ground, creating friction that slows the bike. This friction acts backward (opposite to the direction of motion). Draw an arrow pointing backward (behind the bike), labeled: Friction.

> ✔ *Gravity → Down*
> ✔ *Friction → Backward (opposing forward motion)*

2. Kid sliding down a slide

- Gravity: Pulls the kid downward. Since the slide is tilted, gravity pulls straight down toward Earth. Draw an arrow straight down from the kid. Label: Gravity.
- Friction: Opposes the motion down the slide. So, friction acts up the slide, opposing the slide-down motion. Draw an arrow up the slide, labeled: Friction.

> ✔ *Gravity → Down*
> ✔ *Friction → Up the slide (opposes sliding down)*

3. Roller skating

- Gravity: Pulls the skater downward. Draw an arrow straight down from the person. Label: Gravity.
- Friction: As the skater moves forward, friction between the wheels and the ground helps control motion and prevents slipping. But since she's moving forward, friction acts backward (slightly), opposing motion. However, in roller skating, friction is small, but still present. Draw a small arrow backward (behind her), labeled: Friction.

> ✔ *Gravity → Down*
> ✔ *Friction → Backward (opposes forward motion)*

4. Sledding down a hill

- Gravity: Pulls the person downward toward Earth. Draw an arrow straight down from the person. Label: Gravity.
- Friction: The sled rubs against the snow, slowing it down. So, friction acts up the slope, opposing the motion down the hill. Draw an arrow up the hill, labeled: Friction.

> ✔ *Gravity → Down*
> ✔ *Friction → Up the hill (opposes sledding down)*

---

5. A ball rolling across the ground

- Gravity: Pulls the ball downward. Draw an arrow straight down from the ball. Label: Gravity.
- Friction: The ball rolls forward, so friction between the ball and ground opposes the motion. Draw an arrow backward (behind the ball), labeled: Friction.

> ✔ *Gravity → Down*
> ✔ *Friction → Backward (opposes rolling motion)*

---

6. Pushing a box across the floor

- Gravity: Pulls the box downward. Draw an arrow straight down from the box. Label: Gravity.
- Friction: The box is being pushed forward, so friction opposes that motion. Draw an arrow backward (behind the box), labeled: Friction.

> ✔ *Gravity → Down*
> ✔ *Friction → Backward (opposes pushing forward)*

📝 Summary Table:

| Situation | Gravity Arrow Direction | Friction Arrow Direction |
|----------------------------------|--------------------------|---------------------------|
| Bicycle braking | Down | Backward |
| Kid sliding down a slide | Down | Up the slide |
| Roller skating | Down | Backward |
| Sledding down a hill | Down | Up the hill |
| Ball rolling across ground | Down | Backward |
| Pushing a box across the floor | Down | Backward |

✔ Final Tips for Drawing:

- Gravity: Always vertical, downward.
- Friction: Always parallel to the surface, opposite to motion.
- Use arrows and labels clearly.

You can now draw these arrows on the worksheet accordingly!
