Scientific Overview
Weight is the force exerted on an object due to gravity. It is different from mass, which is the amount of matter in an object. Weight varies with gravitational field strength.
Historical Background
Ancient civilizations used stones, seeds, and metal weights for measurement. The kilogram was originally defined as the mass of one liter of water at 4°C.
Real-World Applications
Commerce
Accurate weight measurements are essential for trade and pricing.
Health
Body weight monitoring is crucial for medical assessments.
Engineering
Structural weight calculations determine load capacities.
Science
Precise weighing is fundamental in chemical experiments.
Transportation
Weight limits ensure safety in aviation and road transport.
Interesting Facts
- The kilogram is now defined by the Planck constant.
- Objects weigh less on the Moon due to lower gravity.
- The heaviest object ever weighed was the Revolving Service Structure of NASA at 2,423 tons.
- A person weighing 68 kg on Earth would weigh only 11 kg on the Moon.
- The concept of weightlessness occurs in free-fall conditions.
