What is inertia on which factor inertia depends?

Inertia depends on density and mass. Inertia is directly proportional to mass and density of an object. More the mass of an object, more is the inertia of the body.

Does inertia depend on velocity?

No, inertia does not depend on speed. Inertia solely depends on the mass. The more mass, the more inertia.

Do all bodies have same inertia?

Answer. all bodies does not have same inertia because inertia depends on the mass of the body. For example it is easy to push or pull or stop a empty box or a book but it is not easy to push or pull or stop a car with the same force you used on the book or box.

What happens to inertia when velocity is doubled?

There is no change in the inertia when the velocity is doubled. Inertia is dependent only on the mass of the object.

Does density affect inertia?

It means that mass is directly proportional to density and volume. So if density or volume is decreased, then mass should also decrease and hence inertia SHOULD decrease.

Is inertia directly proportional to mass?

Inertia is a property of objects: the degree to which they resist changes in their motion. It turns out that the inertia of an object is directly proportional to its mass: the more massive it is, the harder one has to push to move it. Weight is the force exerted downwards by a body in a gravitational field.

What two factors determine an object’s moment of inertia?

Torque depends on three factors: force magnitude, force direction, and point of application. Moment of inertia depends on both mass and its distribution relative to the axis of rotation.

Who gave the concept of inertia?

The law of inertia was first formulated by Galileo Galilei for horizontal motion on Earth and was later generalized by René Descartes.

What is difference between mass and inertia?

Mass is a measure of the amount of matter in an object. Inertia is the resistance of a physical object to any change in its state of motion.

What is the factor that most dramatically influences moment of inertia?

The mass of the implement is definitely farther from the axis of rotation, so the moment of inertia should increase. How can an object (like a human body) have more than one moment of inertia? An object may have more than one moment of inertia because an object may rotate about more than one axis of rotation.

On what factors does inertia of an object depends?

Inertia depends on density and mass. Directly proportional to both of them.

Does inertia increase with speed?

4 Answers. For both interpretations, the answer is ‘yes’ since force still acts in an opposite force on anything which has mass. As you accelerate, your velocity increases and therefore mass will increase. … The greater the mass, the greater the inertia.

Does moment of inertia depend on angular velocity?

A. Angular velocity of the body. Hint: Moment of inertia of a body is defined as the quantity which is expressed by the body resisting the angular acceleration which is given as the product of the mass of every particle with its square of the distance from the axis of the rotation. …

Which of the following has more inertia?

The greater is the mass of the body; the greater is its inertia and vice-versa. (a) Mass of a stone is more than the mass of a rubber ball for the same size. Hence, inertia of the stone is greater than that of a rubber ball. (b) Mass of a train is more than the mass of a bicycle.

On what factor does the inertia of a body depends explain with the help of suitable example?

Inertia of a body depends on its mass. A cricket ball has more inertia than a rubber ball of the same size because it has more mass than the rubber ball.

Does inertia depend on mass?

The inertia of an object is a measure of its resistance to a change in the state of its motion. It is solely dependent on the mass of the object, with more massive objects having larger inertia and a greater tendency to resist changes to their motion.

On what factors radius of gyration depends?

On what factors radius of gyration depends? Some of the factors that influence the value of the radius of gyration are the size and shape of the body, configuration of the rotational axis and position. It also depends on body mass distribution with respect to the rotational axis.

What is the physical significance of moment of inertia?

The physical significance of the moment of inertia is similar to the mass in the translational motion. In translational motion, the mass of a body is used for measuring the inertia. As the mass increases, inertia becomes larger. The force required for producing the linear acceleration will also increase.

What causes inertia?

Some sort of a local field, maybe not our A field, is really the cause of inertia. When you push on an object a gravitational disturbance goes propagating off into either the past or the future. Out there in the past or future the disturbance makes the distant matter in the universe wiggle.
