Why does Weight equal Mass x Gravity?

Question

My teacher just said as the bell went and I don't know why it is so.

Answer 1

Mass and weight are proportional to each other. The more mass, the more weight. But weight is really the force of gravity acting on an object. Mass is the amount of matter in an object. I really can't EXPLAIN how that equation works because from what I can see it doesn't make sense.

But just know this:

1) Mass and weight are proportional to each other (about the same).
2) Weight is the gravitational force exerted on an object.
3) Mass is the amount of matter in an object.

Answer 2

Now look, most high school frosh know that answer. It's because it does. Thats why. Look son, the heavier an object is, the more gravity it will have on this sweet earth of ours. Like. if I am 260 lbs and you are 140 lbs, there will be less gravitational pull upon the earth for you than me. Thus, Wt equal Mass x Gravity. Now this is plain talk. Some smart professor will explain it so that you will be even more confused and thats why they won't accept a simple answer. Like the guy at the top of these answers.

Answer 3

Weight = Mass*Gravity

You see mass is the "matter", ( what something is made up of)
The mass of an object stays the same wherever it is. But the weight changes depending on the amount of gravity acting upon the object.

e.g when you are on a different planet your weight will be different because the gravity of that planet is different, but your mass will still be the same.

that is why the generel equation for working out the weight of something is Mass*Gravity. Because it works wherever you are.

Hope that helped.

Answer 4

weight is equal to mass x gravity because the acceleration due to gravity pulls every object on the surface of the earth towards the centre of the earth. Every object has a mass . when an object is pulled towards the centre of the earth, it is said to have weight. and this weight consists of the mass of the body and the acceleration due to gravity. it is well known that f=ma. therefore w=mg. where weight is the force of gravity on the object

Answer 5

confident, weight is an occasion of a tension. tension could be mass * gravity. yet of direction there could be different forces. So the comprehensive tension on an merchandise could be something different than mg. And to your extra advantageous question. if g= a ie in loose fall, then mg = ma gravity is purely an acceleration which might happen interior the absence of alternative forces. So in this concern the two expression extremely supplies the internet tension on an merchandise.

Answer 6

This is because of the formula:

F= m x g

where F=force, or in your case, F=weight, and m=mass and g= gravity ( or acceleration ).

Remember the basic law is:

F = m x a where F=force, m=mass and a=acceleration.

This relationship is also called Newton's 2nd law of motion.

The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector

Answer 7

mass is a measure of the quantity of substance in a material. It is constant. A 5kg bag of rocks is 5kg on earth, on the moon, even in "zero gravity". Weight, on the other hand, is by definition the force of gravity on a mass. Weight varies based on the effects of gravity. So a 5lb bag of rocks weighs considerably less on the moon, and near zero in "zero gravity".

I hope this makes sense :)

Answer 8

as far as i know, it's because weight of a matter depends upon it's mass and the pull of gravity.

Answer 9

lets say a person on earth is 100lbs.... that is so because of their mass and the gravity of earth pulling them down.

they would weigh less on the moon, because the moon pulls a person with less gravity. their mass is still the same, just less of a pull.
