Grade 3 science worksheet on gravity and friction with illustrated scenarios for students to analyze and label forces.

Task Overview:

The task requires you to analyze each situation and draw arrows to represent the pull of gravity and the force of friction. Here's how to approach each scenario:

---

1. Putting on the brakes to stop a bicycle

- Pull of Gravity: The force of gravity acts downward, pulling the bicycle and the rider toward the ground.
- Draw an arrow pointing downward from the bicycle/rider labeled as "Gravity."
- Force of Friction: When the brakes are applied, friction is generated between the brake pads and the wheels, slowing the bicycle down.
- Draw an arrow pointing opposite the direction of motion (backward) at the wheels labeled as "Friction."

2. Kid sliding down a slide

- Pull of Gravity: The force of gravity pulls the kid downward along the slide.
- Draw an arrow pointing downward along the slide labeled as "Gravity."
- Force of Friction: Friction acts upward along the slide, opposing the motion of the kid.
- Draw an arrow pointing upward along the slide labeled as "Friction."

3. Roller skating

- Pull of Gravity: The force of gravity pulls the skater downward toward the ground.
- Draw an arrow pointing downward from the skater labeled as "Gravity."
- Force of Friction: Friction acts horizontally opposite the direction of motion as the skater pushes off the ground.
- Draw an arrow pointing backward (opposite the direction of motion) labeled as "Friction."

4. Sledding down a hill

- Pull of Gravity: The force of gravity pulls the sled and the person downward along the slope.
- Draw an arrow pointing downward along the slope labeled as "Gravity."
- Force of Friction: Friction acts upward along the slope, opposing the motion of the sled.
- Draw an arrow pointing upward along the slope labeled as "Friction."

5. A ball rolling across the ground

- Pull of Gravity: The force of gravity pulls the ball downward toward the ground.
- Draw an arrow pointing downward from the ball labeled as "Gravity."
- Force of Friction: Friction acts horizontally opposite the direction of motion as the ball rolls.
- Draw an arrow pointing backward (opposite the direction of motion) labeled as "Friction."

---

6. Pushing a box across the floor

- Pull of Gravity: The force of gravity pulls the box downward toward the floor.
- Draw an arrow pointing downward from the box labeled as "Gravity."
- Force of Friction: Friction acts horizontally opposite the direction of motion as the box is pushed.
- Draw an arrow pointing backward (opposite the direction of motion) labeled as "Friction."

Final Answer:

For each scenario, draw and label the arrows as described above. Here’s a summary of the directions for each:

1. Putting on the brakes to stop a bicycle:
- Gravity: Downward
- Friction: Backward (opposite motion)

2. Kid sliding down a slide:
- Gravity: Downward along the slide
- Friction: Upward along the slide

3. Roller skating:
- Gravity: Downward
- Friction: Backward (opposite motion)

4. Sledding down a hill:
- Gravity: Downward along the slope
- Friction: Upward along the slope

5. A ball rolling across the ground:
- Gravity: Downward
- Friction: Backward (opposite motion)

6. Pushing a box across the floor:
- Gravity: Downward
- Friction: Backward (opposite motion)

Final Answer: \boxed{\text{Draw arrows as described above for each scenario.}}
