Is mass how heavy something is?

Answer 1

No. Weight is dependent on both mass and gravity (weight= mass x acceleration due to gravity). For example, if you went to the moon you would weigh less because the gravity is weaker, but your mass would be the same.

Answer 2

Yes there is.

Mass is the amount of matter in an object. Weight is the gravitational force exerted on an object by the larger object on which it rests. Said another way, weight is mass in a gravimetric field.

• The force is given by f = G m1m2 / d2 where
• G is the universal gravitational constant
• m1 is the mass of one the objects
• m2 is the mass of the other object
• d is the distance between the centers of mass of the two objects.

Notice that this formula is symmetric; the force on the larger body by the smaller is identical to the force exerted on the smaller body by the larger. Back to Newton's third law - action and reaction are equal and opposite.

Notice also that because of the way in which the units were chosen, on the surface of our earth mass and weight have the same value. A 100Kg mass weighs 100Kg on the earth's surface. Take it to the moon; it will still have a mass of 100Kg, but weigh only about 15Kg.

N.B. In reference to the above, technically, mass is measured in kilograms, but weight in Newtons. So a 100kg mass would still have a mass of 100kg on the moon, but its weight on both surfaces should be measured in Newtons. In everyday use, people use kilograms to describe weight without realising they are actually talking about the mass of an object.

Answer 3

Yes!

It means:

1.) a large number of people or things together.

2.) in physics, the mass of an object is the amount of physical matter

contains.Mass is measured in grams or ounces.

3.) the ordinary people. This show designed to appeal to the masses.

Answer 4

no, weight is the pull of gravity on an object while mass is the actual object in simplified terms

Answer 5

mass and anything that takes up space and has weight.

Answer 6

Yes.

Answer 7

yes it is
