As a subject matter expert in physics and engineering, I am well-versed in the concepts of force, mass, and their interrelations. When discussing weight, it's important to distinguish between the concept of mass and the concept of weight. Mass is a measure of the amount of matter in an object, and it's typically measured in kilograms (kg). Weight, on the other hand, is the force exerted on an object due to gravity and is a vector quantity, meaning it has both magnitude and direction. In the International System of Units (SI), the unit for weight is the Newton, abbreviated as N.
The Newton (\( N \)) is named after Sir Isaac Newton, the renowned physicist who formulated the laws of motion and universal gravitation. It is the standard unit of force in the SI system. To understand the relationship between mass and weight, we can refer to Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration (\( F = ma \)). On Earth, the acceleration due to gravity (g) is approximately \( 9.8 \, \text{m/s}^2 \). Therefore, the weight of an object can be calculated by multiplying its mass by the acceleration due to gravity (\( W = mg \)).
Let's consider the example provided: a 1 kilogram mass on Earth. According to Newton's second law, the weight of this object is \( 1 \, \text{kg} \times 9.8 \, \text{m/s}^2 = 9.8 \, \text{N} \). This means that a 1 kg mass exerts a force of approximately 9.8 Newtons due to the gravitational pull of the Earth. Similarly, a 100 kg mass would exert a force of \( 100 \, \text{kg} \times 9.8 \, \text{m/s}^2 = 980 \, \text{N} \), which is about 980 Newtons.
It's crucial to note that the weight of an object can vary depending on the gravitational force it experiences. For instance, an object would weigh less on the Moon due to the Moon's lower gravitational pull compared to Earth's. This is why astronauts can leap much higher on the Moon's surface.
In practical applications, understanding the difference between mass and weight is essential for various fields, including construction, aerospace, and sports. Engineers must calculate the forces acting on structures to ensure their stability. Astronauts and spacecraft designers must account for the changes in weight during space missions. Athletes and coaches consider the force exerted by gravity when training and competing.
In conclusion, the N in weight stands for Newton, a unit of force that is directly related to the mass of an object and the acceleration due to gravity. It is a fundamental concept in physics that has wide-ranging implications in our understanding of the natural world and the design of technologies and systems that interact with it.

The correct unit for force is the Newton (=1 kg. -- m/s2) which is abbreviated N. Gravity makes a 1 kilogram mass exert about 9.8 Newtons of force. So a 100kg mass really weighs about 980 Newtons on Earth.
