B. State whether the following statements are true (T) or false (F).

1. A motor is used to create light in a circuit.

2. Linear motion refers to movement in a straight line.

3. Connectors are used to assemble blocks without any electrical
functions.

4. An IC engine valve helps control the flow of gases in an engine.

5. Gears are not important for mechanical movement in robots.

C. Fill in the blanks.

1. A is a device that transforms electrical energy into mechanical
movement.

2. The mechanism is used to convert rotational motion into linear
motion

3. motion occurs when an object moves back and forth repeatedly.

4. Connectors allow the flow of between different parts of a circuit.

5. A is a type of motion that occurs when an object moves in a straight
line.

1. Scenario 1: You have built a simple car model using the block-based

construction kit. During testing, the car moves in circles instead of a straight
line. What might be the issue, and how can you fix it?
2. Scenario 2: You are designing a robotic arm that uses a cam and follower

mechanism. Describe how you would ensure that the arm can lift objects
smoothly and efficiently. What factors would you consider in your design?
