It means that if one increases, so will the other. More precisely, if one increases by a certain factor, the other will increase by the same factor.The relationship is as follows:
weight = mass x gravity
Basically, if the gravitational attraction doesn't changes, for example you are observing two different masses close to Earth's surface, then gravity (which close to Earth's surface is about 9.8 newton/kilogram) can be said to be the "proportionality factor".
In general, if a number "b" is proportional to another number "a", that means that there is a constant "k" such that:
b = ka
("b" is equal to "a", multiplied by the proportionality factor).
The statement is true only in a limited sense. The weight of an object is the product of its mass and the force of gravity. If - and only if - the force of gravity remains the same, then weight is a simple multiple of the mass and therefore the statement is equivalent to saying that weight is a simple multiple of mass.
Unfortunately, the force of gravity on earth is NOT the same. It depends on the distance from the centre of the earth to the surface. Since the earth is not a perfect sphere but somewhat flattened, objects at the poles weigh approx 0.5 % more than at the equator even though the mass is unchanged. An objects taken up a mountain will have a lower weight than at sea level. Finally, there are variations in the density of the earth's crust which will also have an effect on the weight of an object.
If you go away from the surface of the earth, the relationship breaks down completely. An astronaut with a mass of 90 kilograms will weigh approx 880 Newtons on earth, could weigh as little as 0 Newtons while in orbit, weigh approx 145 Newton on the moon. If it were at all possible to travel to a neutron star, the same astronaut would have a weight of almost 1.8 trillion Newton. Same mass, weight ranging from 0 to 1.8 trillion: that is not a description of a proportional relationship!
Hi weight = mass x acceleration due to gravity
At one place acceleration due to gravity remains constant
So weight will be proportional to the mass of the body.
weight (W) = mass (m) x acceleration of gravity (g),or W =mg. This is a direct proportion relation since the g term is a constant - the higher the mass the higher the weight
Because your weight is proportional to the product of your mass and the mass ofwhatever large body you happen to be standing on at the moment. The number you'reused to seeing is your weight when the other body is the earth. If the other body is notthe earth but something different, then your weight is different.
Force is directly proportional to mass provided the acceleration is constant.
directly proportional because force=(mass)(acceleration) (f=ma)
x is directly proportional to y if when x is increased (or decreased) by a relative amount then the same relative change occurs in y. So, if x is doubled, for example, then y is also doubled. Examples are: 1. Weight is equal to mass * gravity. Here mass and weight are directly proportional (when measured in the same gravitational field). For example, if we double the mass then the weight is also doubled. 2. In electronics there is a law called Ohm's Law which states: voltage = current * resistance (V = IR). Here the voltage is directly proportional to both current and resistance. For example, if we halve either the current or resistance then the voltage is also halved. There are lots of other examples you could find.
1/16 of a pound. ~ The fluid ounce of WHAT liquid. Each has their own property and weight. And ounce of whipped cream versus an ounce of liquid mercury is far from each other (example only). Your mass and weight are so far from each other. More information is needed. ~
weight and mass
The relationship between them is as follows. mass = volume x density weight = mass x gravity That means that, other things being equal, mass is proportional to volume. On the other hand, weight is also proportional to mass.
It means that although they are not equal, there is a correlation between them, e.g., mass directly affects weight. If an object has more mass, it will weigh more.
true or false. weight and mass are proportional but not equal
no
Yes, weight is directly proportional to mass, on earth weight = mass X 9.8 or sometimes it is simplified to 10, the unit for weight is newtons (N)
No, weight is a force. Mass is proportional to density.
Yes, weight is directly proportional to mass, on earth weight = mass X 9.8 or sometimes it is simplified to 10, the unit for weight is newtons (N)
As the mass increases, the weight also increases correspondingly as the weight is directly proportional to the mass
Yes... Weight=mass*acceleration
The force of gravity that attracts two objects toward each other is directly proportional to the mass of each object.
The weight of an object is its mass multiplied by acceleration due to gravity. If you assume that acceleration due to gravity is a constant then weight would be a constant multiple of mass and the two measures would be proportional. However, gravitational acceleration varies across the earth: depending on latitude and altitude, as well as the density of rocks underneath and other local geological features. So the assumption about it being a constant is not true.
