# Does weight vary according to the force of gravity?

yes as the wight is directly proportional to gravity.

In fact, weight itself is a force, as force is F=ma, such as weight on earth (or F) is a persons mass times the acceleration due to gravity on Earth (9.8 m/s2), and the force due to gravity changes depending where you are sense force due to gravity is F=G(m1m2/r2). So changing the mass of the planet changes the "weight" (aka force)

## Related Questions No, mass does not vary according to the force of gravity. Mass is a measure of how much matter an object has. Weight, however, is a measure of the force of gravity acting on an object; as such, weight varies according to gravitational field strength. The property of matter that is not affected by gravity is mass. An object has the same mass regardless of the force of gravity, however it's weight can vary. Weight is the force of gravity acting on the mass of an object. It could be said that it is how much force is gravity putting on the object, weight is related to mass and gravity, such that : weight = mass x gravity It is a common mistake thinking that weight is same as mass, mass is the amount of quantity in an object, and doesn't vary according to position as weight does. It means that you put fat on Mass is constant because it is the amount of matter or "stuff" that we are made of. Weight, however, which is the force of gravity on a mass, does vary because the force of gravity varies with location. So your weight would vary, but not your mass. Gravitational force is the force that acts between any two masses in the universe and pull them towards each other weight is the measurement of gravity on an object the more gravity the more weight,an object varies from place to place because gravitational forces vary. Mass is the amount of matter inside an object. Weight is the measurement of the force of gravity (an acceleration) that acts on you. This will vary for a given mass depending on the local gravity field. The weight of an object, in a gravitational field, is a force that is equal to the mass of the object multiplied by the acceleration due to gravity.Weight is the vertical force exerted by a mass as a result of gravity.Weight can be expressed mathematically asFw = mgwhere,Fw = force, or weight, resulting from an accelerating objectm = mass of an objectg = acceleration due to gravityThis equation is a variation of Newton's second law of motion. In the general form of the equation the variable g is replaced by the variable a which stands for any acceleration acting on an object with mass. Whenever an acceleration is caused by gravity, the force on that object is called it's weight.The weight of an object should not be confused with the mass of an object. The mass of an object is constant no matter where in the universe the object is located, but it's weight can vary in different places because the force of gravity can vary depending on location.== == Yes, because if you are 90 pounds on earth you would be 15 pounds on the moon. This is because weight is the force of gravity acting on an object, and the force of gravity depends on the mass of the object. The force of gravity on the earth is six times greater than that of the moon, or, the force of gravity on the moon is 1/6 that of the earth. On earth, a person's weight would vary slightly between sea level and the top of a mountain. This is because the force of gravity is stronger the closer an object is to the center of the earth (or moon, or planet). You use different units for weight and mass because the weight of an object is dependent on the force of gravity and this means that weight can vary depending on where the object is. Mass on the other hand is constant regardless of force of gravity. For example, astronauts are weightless when orbiting the earth but their mass is exactly the same in space as it is on earth. No - it depends on the force of gravity which can vary by up to 5% across the surface of the earth. It's mass will still the same, but as indicated above, gravity varies even on Earth, and that affects weight. Weight is not how much of you there is, that is mass. Weight is the force of gravity fulling you down to the floor. It should, technically, be measured in Newtons and our bathroom scales are actually measuring mass, not weight. Thus, weight varies from planet to planet because each planet's gravitational force is different, stronger or weaker that earth. Weight depends on acceleration due to gravity and similarly acceleration due gravity depends on force of gravity. The force of gravity of moon is 6times less than that of earth and due to this their is variation in acceleration due to gravith between the earth and the moon. As there is difference in acceleration due to gravity between the earth and moon, the magnitude of weight also vary . And next most important thing to keep on mind is that mass is independent of gravity so it does not change anywhere .... Weight is a function of gravity. As a person moves farther away from a source of gravity, such as the earth or moon, the amount of gravitational force they experience dwindles, until it is negligible. While weight is a local property, the person's mass is constant. In other words, while the person is technically "weightless" applying force to create motion will vary based on how "massive" a person is. Weight is measure of the product between the body's mass and acceleration due to gravity acting on it. This acceleration due to gravity is different at different locations on earth. And hence is the weight. Poles are said to have higher acceleration of gravity. Weight is a force and is a product of mass X acceleration. On the Earth acceleration due to gravity is 9.81 m/s^2. So 1 kg x 9.81 m/s = 9.81 Newtons. Note that the weight of 1kg would vary on another planet due to the change of gravity. The mass of an object whether it is living or died will never change in any part of the universe... However, its wright will vary from place to place. Weight is a Force which depends on the gravitational force of the planet. W=mg; where is the mass of the body and g is the force of gravity of the earth. As g changes in any part of the universe, similarly the weight of the object also varies.
