# Weight or Mass?

People often use "weight" to mean "mass", and vice versa, because Gravity is almost the same everywhere on Earth and we don't notice a difference. But remember. they do not mean the same thing, and they can have different measurements. Weight is a Force. Weight W W W W is just another word for the force of gravity F g F_g F g F, start subscript, g, end subscript. Weight is a force that acts at all times on all objects near Earth. The Earth pulls on all objects with a force of gravity downward toward the center of the Earth.

Mass is a measure of the amount of material in an object, being directly related to the number and type of atoms present in the object. Mass does not change with a body's position, movement or alteration of its shape, unless material is added or removed. Mar 01, 2018 · The following definitions of mass and weight can be understood easily: 1. Mass: Mass is the amount of matter contained in a given body and does not vary with the change in its geographical position on the earth’s surface. Direct comparison with a standard mass measures the mass of a body by using a lever balance. 2. Weight: Weight is the.

Oct 17, 2019 · Mass and weight are often considered synonymous, but are in fact two different quantities with different units. A mass definition for kids would be that mass refers to the amount of matter in an object. Weight is just the force that gravity applies to the matter within the object. Weight The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton. Dec 11, 2018 · Body mass index: A key index for relating weight to height. Abbreviated BMI.BMI is a person's weight in kilograms kg divided by his or her height in meters squared. The National Institutes of Health NIH now defines normal weight, overweight, and obesity according to BMI rather than the traditional height/weight charts. Overweight is a BMI of 27.3 or more for women and 27.8 or more for. What does weight mean? weight is defined by the lexicographers at Oxford Dictionaries as A body's relative mass or the quantity of matter contained by it, giving rise to. In scientific terms, weight is a force and uses the newton as its unit. The conventional definition of weight is actually mass, which is the amount of matter something contains. Weight and mass are directly proportionate because the acceleration of gravity stays constant in the formula for weight.

## The Differences Between Mass & Weight for Kids Sciencing.

Weight that is higher than what is considered as a healthy weight for a given height is described as overweight or obese. Body Mass Index, or BMI, is used as a screening tool for overweight or obesity. Mass is commonly measured by how much something weighs. But weight is caused by gravity, so your weight on the Moon is less than here on Earth, while the mass stays the same. Mass is measured in grams, kilograms and, tonnes Metric or ounces and pounds US units. The difference between mass and weight - clarification Ok, hopefully we've cleared up any lingering doubts you may have about the whole mass vs weight debate - mass is a measure of the amount of matter in an object and weight is the amount of force that gravity has on an object. 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.

### What Is the Scientific Definition of "weight"?

May 05, 2015 · Weight is the force generated by the gravitational attraction of the earth on the airplane. But weight, the gravitational force, is fundamentally different from the aerodynamic forces, lift and drag. Newton was able to express the relationship in a single weight equation.
