2025年1月21日 · Weight, gravitational force of attraction on an object, caused by the presence of a massive second object, such as the Earth or Moon. Weight is a consequence of the universal law of gravitation: any two objects, because of their masses, attract each other with a force that is directly proportional

Mass is defined as the amount of matter in an object while weight is defined as the force exerted by an object. SI unit of mass is kilograms while SI unit of weight is Newtons. Object weighing 1 kg mass will have 9.8 N weight.

The most common definition of weight found in introductory physics textbooks defines weight as the force exerted on a body by gravity. [1] [12] This is often expressed in the formula W = mg, where W is the weight, m the mass of the object, and g gravitational acceleration.

In physics, however, there is an important distinction. Weight is the pull of Earth on an object. It depends on the distance from the center of Earth. Unlike weight, mass does not vary with location. The mass of an object is the same on Earth, in orbit, or on the surface of the Moon.

2020年8月25日 · The difference between mass and weight is the mass is a measure of the amount of matter in an object, while weight is a measure of the effect of gravity on that mass. In other words, gravity causes a mass to have weight.

The weight of an object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity, w = mg. Since the weight is a force , its SI unit is the newton. Density is mass/volume.

Weight is the force that acts on mass due to gravity and is therefore measured in newtons (N). Calculating weight and mass. The following equation can be used to calculate the...

Weight is the force of gravity acting on an object due to its mass. The three things that affect gravity are location, location, location.

Weight is measured by a calibrated spring scale. The formula relating mass and weight is W=mg. The mass of an object on the Earth is 100 kg. What is the weight of the object on the Earth? What is the mass of the object on the moon?

2021年8月21日 · We have a special name for the force of gravity acting on a mass; we call it the weight of the object. Substituting the acceleration due to gravity into Newton’s second law, we get an expression for the force of gravity on Earth, or the weight of an object: \[F_g=mg \nonumber \]
