Weight is how heavy something is or how much mass it has. An example of weight is when a person is 100 pounds. A measure of the heaviness of an object.The force with which a body is attracted to Earth or another celestial body, equal to the product of the object’s mass and the acceleration of gravity.

What is weight and its example?
In science and engineering, the weight of an object is the force acting on the object due to gravity.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 are examples of mass and weight?
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. On Mars, there is less gravity to pull on your mass, so you would only weigh 18 kg, or 40lbs.
What are some examples of weight in science?
Weight is a measure of the effect of gravity (or other acceleration) upon an object. The same mass can have a different weight depending on the acceleration. For example, a person has the same mass on the Earth and on Mars, yet weighs only about one-third as much on Mars.
What is weight in simple words?
weight. [ wāt ] n. The force with which a body is attracted to Earth or another celestial body and which is equal to the product of the object’s mass and the acceleration of gravity. A measure of the heaviness of an object.
What is weight in physics class 9?
The weight of a body is the force with which it is attracted towards the centre of the earth. The force of attraction of earth on a body is called as weight.The weight of an object on moon is the force with which the moon attracts the earth.
What is a weight in physics?
Weight is a force acting on that matter . Mass resists any change in the motion of objects. In physics, the term weight has a specific meaning – which is the force that acts on a mass due to gravity. Weight is measured in newtons. Mass is measured in kilograms.
What are 2 examples of mass?
Mass can be best understood as the amount of matter present in any object or body. Everything we see around us has mass. For example, a table, a chair, your bed, a football, a glass, and even air has mass. That being said, all objects are light or heavy because of their mass.
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.You can view the weight as a measure of the mass in kg times the intensity of the gravity field, 9.8 Newtons/kg under standard conditions.
Is 50 kg weight or mass?
On earth your mass is 50kg and your weight (the force you exert on the ground) is 490 Newtons. On the moon your mass would still be 50kg but your weight would be 81 Newtons because gravity is lower.
What is a weight in chemistry?
Weight is a measure of force that is equal to the gravitational pull on an object. The weight of an object is dependent on its location.
What is weight to a kid?

What is meant by human weight?
Human body weight refers to a person’s mass or weight. Strictly speaking, body weight is the measurement of weight without items located on the person.
How do you write weight?
The word weight has two common abbreviations. They are, wt. wgt.
What is weight in physics class 11?
Weight is defined as the force exerted by the gravity on an object. The mass of a substance is constant whereas its weight may vary from one place to another due to change in gravity.
What is weight in science grade 8?
Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s 2 on Earth. The formula for calculating weight is F = m x 9.8 m/s 2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.
What is meant by weight class 6?
unit. Solution: The weight of a body is the force of gravity on it. The weight of a body is not constant,it changes from place to place. The S.I unit of weight is newton (N).
Is FG a 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.
What type of force is weight?
The mass of an object refers to the amount of matter that is contained by the object; the weight of an object is the force of gravity acting upon that object.Weight, being equivalent to the force of gravity, is dependent upon the value of g – the gravitational field strength.
What is the weight of a 2kg object?
Weight of an object in relationship to the mass
We need both gravity and mass to come up with a formula. Here is how to proceed: 1 kg weighs 9.8 Newtons. 2 kg weigh 19.6 Newtons.
What is a real life example of mass?
For example, a ball will have a different weight on the Moon than it would on Earth, but in both cases it would have the same mass. See book on forces for more information about weight. Mass can also be seen as the difficulty of accelerating an object. See book on acceleration.
