súlytömeg

Súlytömeg, also known as weight, is a measure of the force exerted on an object due to gravity. It is a scalar quantity, meaning it has magnitude but no direction. The SI unit of weight is the newton (N). Weight is calculated using the formula W = mg, where W is the weight, m is the mass of the object, and g is the acceleration due to gravity. The acceleration due to gravity varies depending on the location on Earth, but it is approximately 9.81 m/s² at sea level.

Weight is distinct from mass, which is a measure of the amount of matter in an object. Mass is a constant value, while weight can vary depending on the gravitational force acting on the object. For example, an object with a mass of 10 kilograms (kg) will weigh 98.1 newtons (N) on Earth, but only 16.6 N on the Moon, where the gravitational force is much weaker.

Weight is an important concept in physics and engineering, as it is a key factor in the design and operation of structures, vehicles, and other systems. It is also a crucial consideration in fields such as sports, where athletes must be able to lift and move heavy objects with ease. In everyday life, weight is often used interchangeably with mass, but it is important to understand the difference between the two in order to accurately measure and calculate physical quantities.
