# How can mass be defined in terms of inertia?

The mass of a body is the measure of inertia of that body.

### What is the relationship between mass and inertia of an object?

The inertia of a body can be defined as the relunctance of a body to acceleration. The mass of a body can be defined as a measure of the inertia of a body. This is because acceleration = resultant force / mass. So, if mass is greater, the less will be the acceleration of the body and hence the greater the inertia.

### Which has greater inertia a large mass or a small mass?

A large mass. The traditional view is to refer to inertia in terms of Newton's First Law of Motion. However, it became common for Physicists to use the mathematically more useful Newton's 2nd Law of Motion to describe inertia in terms of how difficult it is to change the momentum of a body. The 2nd Law of Motion tells us that Force = Mass x Acceleration. "Inertia" in this context is thus directly proportional to…

### How does mass effect inertia?

As inertia can be defined mathematically as I=mr^2 it implies that inertia is directly proportional to mass that is if mass is increased the inertia is also increased and vice versa. Or in general wordings inertia is a property of an object due to which it oppose any change in its state of rest or motion and this property depends upon mass if mass is large then the inertia will also be large similarly if…

### What is moment of inertia and how does it effect on angular speed?

Moment of Inertia is defined as the product of mass and square of distance from its axis of rotation and it is denoted by I. I=mR2 Moment of Inertia depends upon mass from the axis of rotation of wheel rim e.g because the mass of big bicycle lie away from the axis of rotation of wheel rim.So M.O.I of big bicycle is Small than small Bicycle.

### Can inertia be measured in terms of numbers?

Inertia is a property of mass, and since mass can be measured (normally by kilograms) then inertia can also be measured. All scientific measurements are done with numbers, that is what we mean when we say that we measure something. If you are going to estimate a size without using numbers (as in, that's a really big apple) that is not a measurement.

### What variables contribute to moment of inertia?

The axis about which the body is being rotated and the geometry of the body are important. The further away material (in terms of area) is from the centroid of the body the higher the moment of inertia will be, which is why an I-beam is good in bending. If it's the mass moment of inertia which is used in dynamics for Euler's angular momentum equation. Then the mass of the body is important. The…
