Mass is the amount of matter in an object. Common Units are Kilograms (kg), Grams (g), Tonnes (t), etc.
Weight is the force exerted by gravity on that mass. Common Units include Newtons (N), Pounds-force (lbf), Stones (st), etc. The Formula is
Weight (W)=Mass (m) × Acceleration due to gravity (g)
Where g≈9.8 m/s2 on Earth.
Measurement Methods:
-
- Force Sensors and Load Cells: Used in industrial and laboratory settings for precise weight measurements.
- Scales:
○ Mechanical Scales: Traditional spring-based scales.
○ Digital Scales: Provide quick and accurate weight readings, commonly used in homes and businesses.
Applications:
- Engineering and Construction: Calculating loads and ensuring structural integrity.
- Transportation and Logistics: Determining cargo weight to comply with transportation regulations.
- Everyday Life: Body weight monitoring, cooking ingredient measurements, and more.
