Anyone know what unit inertia is measured in?

Question

Anyone know what unit inertia is measured in?

Answer 1

Inertia is measured in any unit of mass.

Not just kilograms.

Such as megagrams, grams, milligrams, etc.

On my physics final I put Newtons, so I should know by now.

Hope that helps.

Answer 2

Inertia Units

Answer 3

Units Of Inertia

Answer 4

The mass of a body determines the momentum P of the body at given velocity v; it is a proportionality factor in the formula:



P = mv



The factor m is referred to as inertial mass.



But mass as related to 'inertia' of a body can be defined also by the formula:



F = ma



By this formula, the more is mass, the less is the acceleration of a body at given force. Masses m defined by the formulae (1) and (2) are equal because the formula (2) is a consequence of the formula (1) if mass does not depend on time and speed. Thus, "mass is the quantitative or numerical measure of body’s inertia, that is of its resistance to being accelerated".



This meaning of a body's inertia therefore is altered from the original meaning as "a tendency to maintain momentum" to a description of the measure of how difficult it is to change the momentum of a body.

Answer 5

Kilograms. Mass is simply a measure of ineria, thats the only way it can be independant of gravity. If it were newtons, then the normal force would vary based on the gravitational feild that the object is experiencing. An objects mass (thus its inertia) is constant anywhere in the universe.

Answer 6

Inertia is scientific principle and not a property of matter. It is not quantifiable in the way you are suggesting, and it has no units.



Inertia is the principle that a body will continue to move in the same way (that is, at the same velocity) unless acted on by a force.

Answer 7

Inertial Measurement Unit. IMU

Answer 8

It is measured in Newtons or Joules. For comparison the conversion factor for Joules is:

1 Joule = 1 watt/second

1 BTu = 1055 Joules



The formula for calculating inertia (kenetic energy) in Joules is:



KE = .5 * (Mass in Kg) * Speed squared (in meters per second)

Answer 9

Basically inertia is mass * (distace)^2 so its unit is Kg m^2

Answer 10

it is measured in kg. inertia is a property of mass.

Units of mass...kilograms, slugs, centigrams, metric tonnes...are the units of inertia.

Answer 12

I agree with geo. It is measured in the same units of mass (i.e. Kg in SI units)

Answer 13

I = kg*m^2

Not mass, not force, not momentum or anything like that...

Interia has its own set of units.

Answer 14

inertia has the dimensions of mass

Answer 15

newtons

Answer 16

i think it is newtons

Answer 17

KILOGARM(Kg)
