What is the difference between mass and weight of an object. will the mass and weight of an object on the earth be same as their values on mars? why?

What's the difference between weight and mass? Many people use these terms interchangeably, but that only works because all but a few of us live on Earth. If we start taking up residence Mass: If you could count up the number of protons, neutrons, and electrons in an object (which you probably can't), this would be a measure of the mass. The mass is essentially "how much stuff" is in an object. Yes, I know that's just a partial definition—but it's good enough for now. Common units for mass are the kilogram and the gram. If you insist on using silly imperial units, the unit for mass is the Weight: There is a gravitational interaction between objects that have mass. If you consider an object interacting with the Earth, this force is called the weight. The unit for weight is the Newton (same as for any other force). OK, fine—the stupid pound is also a unit for weight. In this expression, g is the local gravitational field. The key word here is "local." This calculation of the gravitational force only works on the surface of the Earth. It doesn't work (at least not very well) for 100 kilometers above the surface of the Earth and it doesn't work on Mars. Only on the surface of the Earth is there a proportionality constant of 9.8 Newtons per kilogram. Since most humans live on the surface of the Earth, no one really complains about using "weight" and "mass" to basically mean the same thing. Rhett Allain But wait! Sometimes this doesn't even give you the weight. What if the scale...

Do you know the difference between mass vs weight? A physical body’s mass is the total amount of matter it contains. Solids, liquids, gases, and plasmas are the four basic forms of matter. In addition to taking up space by taking up a volume, matter is defined as anything with at least one mass. The Earth attracts everything towards its center, no matter its state. Also, just as life is attracted to the Earth, its center is also attracted to celestial objects. A force is always attracted to like there are different celestial objects which are attracted by different forces. It is also true that the attraction force varies with a celestial object’s distance from the center. The force responsible for attracting material towards the Earth’s center is called weight. As a result, mass and weight are two different things in the true sense of the word. Why People Confuse about in Mass vs Weight? You can easily do this when you are not entirely certain how science defines them exactly. Even though they are related, there is a fundamental difference between them. In physics, mass is a measure of how much matter is in an object and weight is a measure of how much force gravity exerts on an object. Mass vs weight what difference unit how calculate Image: ksa.mytutorsource.com You’re aware of your weight and have spent hours agonizing over how much muscle you built during your last gym visit as you are conscious of your weight every day. Mass and weight are two words that we frequently...

For the most part, when comparing mass and weight on Earth—without moving!—the values for mass and weight are the same. If you change your location with respect to gravity, mass will remain unchanged, but weight will not. For example, your body's mass is a set value, but your weight is different on the Moon compared with on Earth. Mass is a property of matter. The mass of an object is the same everywhere. Weight depends on the effect of gravity. Weight increases or decreases with higher or lower gravity. Mass can never be zero. Weight can be zero if no gravity acts upon an object, as in space. Mass does not change according to location. Weight varies according to location. Mass is a scalar quantity. It has magnitude. Weight is a vector quantity. It has magnitude and is directed toward the center of the Earth or other gravity well. Mass may be measured using an ordinary balance. Weight is measured using a spring balance. Mass usually is measured in grams and kilograms. Weight often is measured in newtons, a unit of force. How Much Do You Weigh on Other Planets? While a person's mass doesn't change elsewhere in the solar system, the acceleration due to gravity and weight varies dramatically. The calculation of gravity on other bodies, as on Earth, depends not just on mass but also on how far the "surface" is from the center of gravity. On Earth, for example, your weight is slightly lower on a mountain top than at sea level. The effect becomes even more dramatic for large bod...

For example, our medical records often show our weight in kilograms but never in the correct units of newtons. In physics, however, there is an important distinction. Weight is the pull of Earth on an object. It depends on the distance from the center of Earth. Unlike weight, mass does not vary with location. The mass of an object is the same on Earth, in orbit, or on the surface of the Moon. Units of Force The equation F net = m a F net = m a is used to define net force in terms of mass, length, and time. As explaine...

Difference between mass and weight of an object is as follows: No. Mass Weight 1. Mass is the amount of matter contained in a body. Weight is the force exerted on a body due to the gravitational pull of another body such as Earth, the sun and the moon. 2. Mass is an intrinsic property of a body. Weight is an extrinsic property of a body. 3. Mass is the measure of inertia. Weight is the measure of force. 4. The mass of a body remains the same everywhere in the universe. The weight of a body depends on the local acceleration due to gravity where it is placed. 5. The mass of a body cannot be zero. The weight of a body can be zero. 6. The SI unit of mass is the kilogram (kg). Since weight is a force, its SI unit is the newton (N). 7. The mass of a body can be measured using a beam balance and a pan balance. The weight of a body can be measured using a spring balance and a weighing machine.

The mass of an object on the Earth will be same as that on Mars but its weight on both the planets will be different. This is because the weight (W) of an object at a place depends on the acceleration due to gravity of that place i.e. W= mgor W ∝ g and since the values of acceleration due to gravity on both the planets differ, thus the weight of the object will be different for both the planets.
