Worksheet 2: Simple Machines

---

1. Place the name of each simple machine under its image.

We are given six images and six names:
wheel, wedge, lever, pulley, ramp, screw

Let’s identify each one:

#### Image 1: A block on a slanted surface (inclined plane)
- This is a ramp.
- A ramp is an inclined plane used to move objects up or down with less effort.

✔ Answer: *ramp*

#### Image 2: A spiral-shaped object with a head (like a bolt)
- This is a screw.
- A screw is a type of inclined plane wrapped around a cylinder.

✔ Answer: *screw*

#### Image 3: A circular object with spokes (like a tire)
- This is a wheel.
- A wheel is a circular object that rotates around an axle.

✔ Answer: *wheel*

#### Image 4: A seesaw-like structure with a fulcrum
- This is a lever.
- A lever consists of a rigid bar pivoting around a fulcrum.

✔ Answer: *lever*

#### Image 5: A triangular shape (pointed at one end)
- This is a wedge.
- A wedge is a triangular-shaped tool used to split or hold things apart.

✔ Answer: *wedge*

#### Image 6: A system of wheels and ropes (used for lifting)
- This is a pulley.
- A pulley uses a wheel and rope to lift or lower objects.

✔ Answer: *pulley*

✔ Answers for Part 1:

1. ramp
2. screw
3. wheel
4. lever
5. wedge
6. pulley

2. Match the simple machines and their definitions.

We have:
- Wheel
- Ramp
- Lever
- Pulley
- Wedge
- Screw

And definitions:
- To lift and lower objects more easily.
- To move things along the ground.
- To move objects along an inclined surface.
- To hold something in a place.
- To lower and raise very heavy objects.
- To break something apart.

Now let's match them correctly:

#### Wheel
- Used to roll and move objects across surfaces.
- ✔ Matches: To move things along the ground.

#### Ramp
- An inclined plane; helps move objects up or down gradually.
- ✔ Matches: To move objects along an inclined surface.

#### Lever
- Used to lift or move loads using a pivot point.
- ✔ Matches: To lower and raise very heavy objects.

#### Pulley
- Helps lift and lower objects with less force using a rope and wheel.
- ✔ Matches: To lift and lower objects more easily.

#### Wedge
- Used to split or separate materials (e.g., axe, knife).
- ✔ Matches: To break something apart.

#### Screw
- Can be used to hold things together or apply pressure (e.g., bolts).
- ✔ Matches: To hold something in a place.

✔ Answers for Part 2:

| Machine | Definition |
|--------|-----------|
| Wheel | To move things along the ground. |
| Ramp | To move objects along an inclined surface. |
| Lever | To lower and raise very heavy objects. |
| Pulley | To lift and lower objects more easily. |
| Wedge | To break something apart. |
| Screw | To hold something in a place. |

✔ Final Answer Summary:

#### Part 1:
1. ramp
2. screw
3. wheel
4. lever
5. wedge
6. pulley

#### Part 2:
- Wheel → To move things along the ground.
- Ramp → To move objects along an inclined surface.
- Lever → To lower and raise very heavy objects.
- Pulley → To lift and lower objects more easily.
- Wedge → To break something apart.
- Screw → To hold something in a place.
