What answer is the best estimate for the mass of a marble?

Answer 1

An electronic balance.

Answer 2

Mass is a fundamental concept in physics, roughly corresponding to the intuitive idea of how much matter there is in an object. Mass is a central concept of classical mechanics and related subjects, and there are several definitions of mass within the framework of relativistic kinematics.

According to Newton's second law, we say that a body has a mass m if, at any instant of time, it obeys the equation of motion;

f = d/dt(mv)

where f is the force acting on the body and v is its velocity.

It can be derived if you know other physical aspects - example

mass = Density X volume

mass = Force / acceleration

mass = momentum / velocity

one regular sized round glass marble & 1cm diameter 3.56g sounds reasonable

but you would have to tell me the size and all that :)

Answer 3

You can weight it of course, but if you want to calculate it you first deed the density of glass.

Then you use the equation

mass = density x volume or m= ρV

Search >glass< in wikipedia to find the density.

Soda- lime glass has a density of 2.52 g/cm³

Now you either need the diameter or the circumference so you can calculate the volume.

You start with the standard equation

v= (4/3)piR³ were pi = 3.14 and R = radius

but depending on whether you use the diameter or circumference you will need the equations

D = 2R

or

C = 2piR

Since your density is in units of g/cm³ your distance will have to be in cm (or centimeters)

If you use the circumference the equation is

m= ρV = 2.52 x (4/3)pi (C/2pi)³

Answer 4

use a scale, make sure you're not in outer space

Answer 5

either put it on a scale or use the formula density=mass/volume

Answer 6

triple beam

Answer 7

the volume of a ball with radius 5 cm and the mass volume 700 kg/m3

Answer 8

The answer should be 3 Kilograms

Answer 9

Balance and gram

Answer 10

balance scale
