can anyone help me explain the formula: D = m/v???

Question

i'm doing a lab report so one of the topics is to explain the formula to find density. I know it's a ratio, but i need for information besides that. Thank you!

Answer 1

m = mass
v = volume

Answer 2

In the formula D = m/v, D denotes density , m denotes mass and v denotes volume.

Therefore Density is mass per unit volume.

In Physics we use the term ratio only if the numerator and denominator are of same quantity.

Density is mass divided by volume and hence it cannot be called as ratio.

When mass is divided by volume we find the mass per UNIT volume.

We determine how much mass will be in each unit volume.

Answer 3

It is a ratio. Density is the mass of a substance(m) in a given volume(v). I would use a upper-case V, which is more commonly in use and not confused with velocity. If you want to be fancy, you can use the small Greek "rho", which looks like a scrip lower "p" for density.

Answer 4

Usually density is p, rho, but it is simply the ratio of mass per unit volume. a higher density means for the same volume one material will have a higher mass than another of different density. iron is more dense than say, wood, therefore having a higher density p. normally mass is kg, and volume in m^3 so density is kg/m^3

Answer 5

Density = Mass / Volume
D = density
m = mass
v = volume

Answer 6

somewhat it potential that mass and potential are 2 facets of a single coin. you're no longer destroying mass and changing it into potential; you're seeing an identical phenomenon as the two mass and potential. One straight away observable demonstration of that's got here across each and all of the time in chemistry. in case you look on the lots of the climate alongside the periodic table, you locate that all of them have oddball values, particularly than including as much as essential numbers reckoning on what share protons and neutrons there are. The "errors" seems to get greater effective and bigger as a results of fact the atoms do. the reason that countless the mass is "lacking" is that that's tied up as nuclear binding potential; that potential it somewhat is protecting the neutrons and protons mutually. in case you look at a nuclear reaction equation for the decay of an isotope, you will locate that the potential released whilst an atom splits is comparable to the mass discrepancy situations c^2. be counted won't be able to be destroyed or created, yet mass isn't an identical ingredient as be counted. that's an observable assets of be counted, and this equation demonstrates that this assets applies to potential to boot.

Answer 7

Density is a mass per unit of volume. To measure the density of a material you must be able to measure its mass(m) and its volume(v). Mass can be measured on a balanced, and the volume can be measured in different ways. In measurements of the densities of liquids and solids, volume is usually measured in cubic centimeters and mass is in grams. Density, then, is expressed in grams per cubic centimeters.

Answer 8

You could set up this experiment to explain how to find the density of an object.

Answer 9

the mass multiplied by the volume equals the density
