Mass and weight are two different quantities and one should not confuse one with the other. Firstly weight is a vector quantity and mass is a scalar and therefore invariant with respect to location. In fact it can be used as a measure of inertia. Weight is equal to the force of gravity acting on a body and does vary with a body's location (altitude, latitude and with the value of gravitational acceleration and so on). This difference can be understood by looking at their respective definitions.
m(gravitational) = W/g and m'(inertial)= F/a
A given body can be weightless (a reaction less state, to be exact) but it cannot be mass less.
Our weight on the moon, for example would be 1/6 that on the earth but our masses on earth or moon would be the same ant it would require the same force to accelerate us on the earth or the moon.
AnswerMass is constant, weight is relative. Two objects with the same mass will weigh differently if one is weighed on the Earth and the other on the Moon, due to gravity.
AnswerThe replies above are from the perspective of Physics. In Chemistry, we don't pay much attention to physics. We're looking at the view of the chemicals' reactions versus how gravity or inertia assists. So in Chemistry the weight of an object is the same as it's mass, assuming we're on earth at the same pressure (which earth = 1 atm). There for If I ask for 1 gram of Silicon, the mass is 1 gram and the weight is also 1 gram.
Mass: the SI unit of mass is the kilogram. The meaning of mass is quantity of matter.
Weight: the SI unit of weight is newton. The meaning of weight is the gravitational force applied to an object.
1 newton (N) is 1 kg.m/s2.
On the Earth surface: weight = mass x 9,80665
Also, while mass is a scalar quantity, weight is a vector quantity hence they aren't the same.
In Physics, both mean different.
Mass is the one is the actual content of any substance. It will never change irrespective of its location. Mass will be same for a given substance in earth, moon or wherever it be)
But, Weight is the fuction of Mass which is a force felt based on the gravitational pull on that particular location.
Example: A object weighing 6 lb in Earth will weigh 1lb in moon. Because the gravity is 6 times less in moon compared to that of earth.
Of course not! While your mass stays the same your weight depends on an attractive force. For example on the Moon you will weight much less than on the Earth but your mass would be constant (of course if you not on a diet:))
well obviosly you just put enough wieght on both sides which should make it so its not tilting more or less on one or the other sides
A neutron and a proton have approximately the same mass.
Atomic mass and molar mass are similar concepts but not the same. Atomic mass refers to the average mass of an atom of an element, while molar mass is the mass of one mole of a substance. The mass number of particles can be the same in certain cases, such as isotopes of the same element which have the same number of protons and different numbers of neutrons.
A scale balance is a device used to measure the mass or weight of an object by comparing it to known weights on the other side of a horizontal bar or beam. It works on the principle of balancing the weights to determine the mass of the object being measured.
Yes, mass percent and percent by mass are the same concept. Both terms refer to the percentage of a component in a mixture by mass.
your mass stays the same. yoir WIEGHT changes
what is preferred in a market. a mass or wieght?
they are realetd because weight is mass and gravity is also mass
no it's wieght
hehehe we just finished this in science. the amount of space taken up by and object is it's mass mass is measured in grams mass is different than wieght, for example in space, you are weightless, but you mass stays the same. :)
B/c weight is dependent o the gravitational pull, while mass has to do with the amount of substance.
lose wieght?
According to the Theory of Relativity, yes - any energy has an equivalent mass; and of course, mass has weight. The equivalent mass for the amounts of heat you encounter in your daily life is insignificant for most purposes.
It is spelled weight. Not Wieght.
because oil have light wieght than water have heavy wieght
The hood or the base of the ship is such that the wieght of the ship is able to displace a large volume of water. the wieght of the water is displaced is equal to the wieght of the ship itself. this displacement of water from its original position develops a potential energy which is the upward force balancing the wieght ot the ship.
