Short-Question

# Does moment of inertia depend on mass?

## Does moment of inertia depend on mass?

The moment of inertia depends not only on the object’s mass, but also the distribution of that mass in relation to the axis of rotation. The moment of inertia of an object usually depends on the direction of the axis, and always depends on the perpendicular distance from the axis to the object’s centre of mass.

On which factor moment of inertia depends on?

The moment of inertia of a body is directly proportional to its mass and the distance of the particles of the body from the axis of rotation. Hence, the moment of inertia depends on mass and distance from the rotating axis, and force and density do not affect the moment of inertia of a body.

What are two factors on which moment of inertia depends?

The moment of inertia depends on the following factors,

• The density of the material.
• Shape and size of the body.
• Axis of rotation (distribution of mass relative to the axis)

### What is the relationship between inertia and velocity?

Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object’s speed, or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed when no forces act upon them.

Is inertia depend on shape?

Thus, the moment of inertia of the pendulum depends on both the mass m of a body and its geometry, or shape, as defined by the distance r to the axis of rotation. An arbitrary object’s moment of inertia thus depends on the spatial distribution of its mass.

Does moment of inertia depend on torque?

All of the mass m is at a distance r from the center. Moment of inertia also depends on the axis about which you rotate an object. This equation is actually valid for any torque, applied to any object, and relative to any axis. As can be expected, the larger the torque, the larger the angular acceleration.

#### Does inertia depend on shape?

Thus, the moment of inertia of the pendulum depends on both the mass m of a body and its geometry, or shape, as defined by the distance r to the axis of rotation.

What is the relationship between inertia and matter?

Think of inertia as the ability of an object to resist change or moving. A bigger object will be harder to move than a smaller object. So the bigger objet has more inertia. The bigger object also has more matter. Therefore the more matter the more inertia.

What is a simple example and meaning of inertia?

Inertia is the resistance of the object to any change in its motion , including a change in direction. An object will stay still or keep moving at the same speed and in a straight line, unless it is acted upon by an external unbalanced force . For example, a rubber ball will not start bouncing around unless someone picks it up and throws it.

## What are the effects of inertia?

Inertia’s Effects. Inertia keeps your vehicle moving until some force slows it down or stops it. This force can be your own action of applying a brake, the conditions of the road, an object on the road like fallen tree or, if the driver isn’t paying enough attention, even another vehicle.

What are some everyday examples of inertia?

Examples of Inertia in Daily Life (i). Satellites. (ii). Falling of fruits and leaves. (iii). Dusting a carpet. (iv). Falling forward while getting down from a moving bus. (v). The continued swirling of milk after the stirring is stopped. (vi). Running of an athlete before taking a long jump. (vii). An object thrown outside a moving train. (viii).
