# What is meant by weight in science?

weight, gravitational force of attraction on an object, caused by the presence of a massive second object, such as the Earth or Moon.

## What is weight in own words?

1. the amount or quantity of heaviness or mass; amount a thing weighs. 2. Physics. the force that gravitation exerts upon a body, equal to the mass of the body times the local acceleration of gravity: commonly taken, in a region of constant gravitational acceleration, as a measure of mass.

## What is an example of weight in science?

Weight is the measure of the force of gravity on an object. The mass of an object will never change, but the weight of an item can change based on its location. For example, you may weigh 100 pounds on Earth, but in outer space you would be weightless.

## What is mass and weight in science?

In scientific contexts, mass is the amount of “matter” in an object (though “matter” may be difficult to define), whereas weight is the force exerted on an object by gravity.

What is meant by weight in science? – Related Questions

## What is difference between weight and mass?

The terms “mass” and “weight” are used interchangeably in ordinary conversation, but the two words don’t mean the same thing. The difference between mass and weight is that mass is the amount of matter in a material, while weight is a measure of how the force of gravity acts upon that mass.

## What is an example of mass and weight?

Mass is a measure of all the matter that makes up an object, and weight how much gravity is acting upon an object. Since we’re on Earth and used to measuring things on Earth with Earth’s gravity, if your mass is 50 kg, we say that you weigh 50kg. A scale on Earth would read 50kg, or 110lbs.

## Which quantity is weight an example of?

Weight is an example of the quantity of mass.

## What is weight in science grade 7?

Weight is a force caused by gravity. Because it is a force, it is also measured in Newtons (N). It is the gravitational force between the object and the Earth.

## What is weight of a body?

“The weight W of a body is equal to the magnitude Fg of the gravitational force on the body.” The gravitational acceleration varies from place to place. Sometimes, it is simply taken to have a standard value of 9.80665 m/s2, which gives the standard weight.

## How is weight measured?

In common usage, human body mass is often referred to as weight. In fact, weight is the force exerted on an object due to gravity (SI unit = newton, N). A measure of weight in N allows estimation of human body mass in kg using the formula W = m*g and standard gravity.

## What is meant by weight answer in one sentence?

weight. [ wāt ] The force with which an object near the Earth or another celestial body is attracted toward the center of the body by gravity. An object’s weight depends on its mass and the strength of the gravitational pull.

## What is the weight of an object?

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.

## What is a fact about weight?

Since weight is the force of gravity pulling on an object, items weigh much less on the moon than they do on Earth. What is this? If you weigh 80 pounds (36 kilograms) here on planet Earth, you will weigh closer to 13 pounds (six kilograms) on the moon.

## What is the force of weight?

Weight W is just another word for the force of gravity F g F_g Fg​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.

## What are the characteristics of weight?

Characteristics of weight :

=> Weight is a vector quantity. => Weight is measured with a spring balance, or on a weighing machine. => The weight of a body is directly proportional to its mass. =>The weight of body changes with the value of “g”.

## Is mass can be zero?

Mass of a body is defined as the quantity of matter contained in it. Since, all bodies are made up of certain matter. Thus mass of body can never be zero.

## What is weight measured in?

Weight is a measure ofthe force of gravity on a physical object and is measured in newtons.
