The more speed an object possess, the more energy is needed to change that speed. Eg. a car going 100km/h will need more energy to stop than a car going 40km/h. The faster something is travelling, the more resistant it will be to a change in its motion (inertia).

Did inertia depends on the speed?

Inertia does not depend on speed. Inertia is an object's resistance to a change in its state of motion, and it is determined by its mass. The greater the mass of an object, the greater its inertia, regardless of its speed.


What property does inertia depend on?

Inertia depends on the mass of an object. The greater the mass, the greater the inertia.


Does a train have less inertia than a car?

Inertia is related to speed and mass; a train is both faster and more massive than a car.


On what factor does the inertia of a body depend?

inertia simply depends upon mass.


What is inertia on which physical quantity does it depend?

Inertia is the tendency of an object to resist changes in its motion. It depends on the mass of the object, with greater mass leading to greater inertia.


What does inertia varies depend on?

Inertia varies depending on an object's mass. The greater the mass of an object, the greater its inertia. The shape and size of an object can also affect its inertia.


Which is harder to stop vehicle greater mass or less mass?

The greater the mass the greater the inertia. Thus if both vehicles were travelling at the same speed the vehicle with the greater mass would have the most inertia and thus be the hardest to stop.


If speed doubles does inertia change?

No, inertia does not change when speed doubles. Inertia is an object's resistance to changes in motion, and it depends on the object's mass, not its speed.


What does an objet's inertia depends on it?

Mass & speed.


What does the inertia of and object depend on?

An objects mass is a measure of its inertia.


Does speed determine how much ineria an object has?

No, speed alone does not determine how much inertia an object has. Inertia is the resistance of an object to changes in its state of motion, and it depends on the mass of the object. An object with more mass will have more inertia, regardless of its speed.


Does Inertia act to everything?

Inertia is a characteristic of anything that has mass, so the answer may depend on how you define "everything."
