/ (weɪt) / noun. a measure of the heaviness of an object; the amount anything weighs. physics the vertical force experienced by a mass as a result of gravitation. It equals the mass of the body multiplied by the acceleration of free fall.

What is weight in science unit?

The unit of measurement for weight is that of force, which in the International System of Units (SI) is the newton. For example, an object with a mass of one kilogram has a weight of about 9.8 newtons on the surface of the Earth, and about one-sixth as much on the Moon.

What is weight in science for kids?

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.

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 a weight simple definition? – 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 weight?

Weight is how heavy something is or how much mass it has. An example of weight is when a person is 100 pounds.

What is mass and weight for kids?

How do you explain mass?

What are 5 differences between mass and weight?

Complete step-by-step solution:

Mass

Weight

5. Mass is a scalar quantity. It does not have direction. It possesses the only magnitude.

5. Also, the weight, being a force, is a vector quantity i.e. it has both direction and magnitude and its direction is towards the center of the earth.

We know that weight is equal to the product of mass and gravitational force applied. So, W = MG where w is the weight, M is the mass, and G the gravitational force. Hence, it can also be interpreted as ‘the weight of an object is directly proportional to its mass’.

What is the formula of 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.

How is weight measured?

Weight is a measure ofthe force of gravity on a physical object and is measured in newtons. The weight of a bird of mass 15 g varies with the magnitude ofthe gravitational force acting on it and would be considerably different if measured on the Moon, for example, instead of on Earth.

What is the force of weight?

Weight W is just another word for the force of gravity F g F_g FgF, 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.

Is gravity same as weight?

Weight is a quantity that you measure for a particular object, while gravity is a measure of how curved is the spacetime where that object is living.

Is matter a mass or weight?

In science, matter is defined as anything that has mass and volume. Mass is commonly confused with weight. The two are closely related, but they measure different things. Whereas mass measures the amount of matter in an object, weight measures the force of gravity acting on an object.

How weight is related to gravity?

On Earth, the weight of the body (like any other object) is given by Newton’s laws as mass times gravitational acceleration (w = m * g). That is, the weight of an object is determined by the pull of gravity on it.

Does weight depend on mass?

Weight is a measurement of the gravitational force on an object. It not only depends on the object’s mass, but also on its location. Therefore, weight is actually a measure of force. In the United States, most people measure weight in pounds.

Does weight depend on height?

In most of the populations, BMI is not independent of height; weight does not universally vary with the square of height; and the relationship between weight and height differs significantly between males and females.

What is mean by weight of 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.

What is meant by weight answer in one sentence?

Weight is the force exerted on a body due to the gravitational pull of Earth.

Is weight a physical quantity?

It can be expressed as $w=mg$, where m is mass of the object and g is the acceleration due to gravity. So, we can define weight as a force with direction towards the centre of the planet. weight has both the magnitude and direction. Hence, weight is a vector quantity.
