🔍 Key Concepts
• Relationship between displacement, velocity, and acceleration in physics and mechanics
• How motion or vibration of machinery is typically measured on ships
• What kinds of devices are used to monitor machine condition (like bearings, shafts, and rotating equipment)
💭 Think About
• Think about what physical quantity is described when you talk about displacement, velocity, and acceleration together—are these electrical, digital, or mechanical terms?
• On board a vessel, which of these choices would logically need to measure motion over time for maintenance and safety?
• Which options (filters, multiplexers, vibration sensors, RAM) are more related to electronics and data handling rather than mechanical motion?
✅ Before You Answer
• Verify which option is directly associated with measuring motion or vibration in machinery.
• Check which choices are mainly components of electronic signal processing or data storage rather than mechanical sensing.
• Confirm that displacement, velocity, and acceleration are all standard units used in vibration monitoring of rotating equipment.
