Why do objects of same size have different weights?
Why do objects of same size have different weights?
Answer: It comes from the atomic weight of the atoms composing an object and how closely packed is the material composing that object. The old trick question, what weighs more, a pound of feathers and a pound of iron, plays off this property to confuse which is heavier when they weigh the same, a pound.
How can objects of the same size have different masses?
The mass of an object is equal to its volume times the (average) density. Two objects of the same size can have different masses, and can have the same mass when very different in size: it’s all in the different densities.
Can you find two objects that have the same weight but different size?
Oh yes ! Just the volume will differ to accommodate the density difference. So a denser object will need a lesser volume to contain the same mass as an object with lower density, which will need a greater volume to contain the same mass.
Why do objects vary in looks and size?
Why does the size of an object look the same despite changes in viewing distance? Among the things we experience in daily life, nothing appears to be simpler than perceiving the sizes of visual objects. This phenomenon, called size constancy, occurs because our brains combine image size and distance information.
Does size affect weight?
Most weight charts take into effect your frame size. Many weight charts have 10 pound increments in each frame size; small, medium, and large. That is a 30 pound swing for any given height, so if you look at the chart and say to yourself, “I’m big boned and should weight more than that”, well, maybe 10-15 pounds.
Do cubes of exactly the same size and shape have the same mass?
Terms in this set (25) What is Density? Do cubes of exactly the same size and shape, have the same mass? Both cubes are exactly the same size.
What are two objects that are the same shape?
Answer: Congruent. Two figures are congruent if they have the same shape and size. Two angles are congruent if they have the same measure.
What happens if two objects have the same density?
If the object is of equal density it will sink into the water so that no part of the object is above the surface. It may or may not “float” just but entirely below the surface.
Is size and mass the same?
Is mass the same as size? No, mass is different than size or volume. This is because the type of atoms or molecules as well as their density helps to determine the mass.
Why do further objects look smaller?
As an object gets closer, the visual angle increases, so the object appears larger. As the object moves farther away, the visual angle decreases, making the object appear smaller. An item at the bottom of the cone (farther away) will take up less of your field of vision and appear smaller.
How much do DD cups weigh?
For many women, this has been a burdensome trend. A pair of D-cup breasts weighs between 15 and 23 pounds — the equivalent of carrying around two small turkeys. The larger the breasts, the more they move and the greater the discomfort.
Why are objects of the same size and shape identical?
That all depends upon their density (i.e., their weight, since their dimensions are identical). If they both weigh more than the weight of an existing volume of water, they would both sink, and displace an identical amount of water, because they cannot displace any more than that.
What’s the difference between mass and weight of an object?
Mass refers loosely to the amount of “matter” in an object, and weight refers to the force exerted on an object by gravity. In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. In scientific contexts, mass is the amount of ” matter ” in an object …
What happens if you float two same size objects?
Now, if you are talking about floating two same sized objects of different densities, then the denser object would sink further into the water. What’s happening is that, in order to float, an object must displace a given volume of water equal to its own mass.
Can a same size object sink into the same water?
Using lab conditions, same sized objects of the same volume, will displace the the same volume of water, if completely submerged. Now, if you are talking about floating two same sized objects of different densities, then the denser object would sink further into the water.

Why are two objects have the same mass but with different volumes?
When two objects have the same mass but with different volumes, the one with smaller volume will be more dense, Why? It can all be attributed to the definition of density. Density is defined as the mass per unit volume. This definition implies dividing the mass by the volume.
Now, if you are talking about floating two same sized objects of different densities, then the denser object would sink further into the water. What’s happening is that, in order to float, an object must displace a given volume of water equal to its own mass.
