Inertia is a force

Put simply, inertia is the measure of an object's reluctance to change its state of motion. The object's state of motion may be stationary or flying through space at 20,000 km/hr. The unit for measuring inertia in the SI is the same as for mass: the Kilogram. Inertia (mass) can be expected to increase when an object is traveling at relativistic (near the speed of light) speeds.

Supervisor's note: The following answer is looking for a clear-headed makeover.

Inertia is NOT a force because Inertia just is the resistance to change in motion. An object's inertia never changes.

Here is something to think about so you can answer the question yourself...

If you slide a pencil on the floor away from any object that could block it the pencil still stops. Do you think it is because gravity or inertia did it? No. The thing is inertia is just like the Law of conservation. All objects,energy, etc. follow it but inertia is not A FORCE that stops a car when it hits a wall. It is an outside force like friction which is what stoped the pencil from countinuing to slide on the ground. An object's inertia can change but not it's amount, because there is no amount of inertia because like i said before inertia is like a law, all objects have inertia (meaning they all follow the rule of inertia) If there were no other outside force like gravity and friction then when we could not accelarate and there would be no inertia. I know this paragraph makes no sence but to me this is how i look at inertia. As a law or property of matter and not a force. One last thing to think about. Does inertia change anything... if so write a disscusion and tell me what you think it changes and if a car crashes DID INERTIA CAUSE THAT...

What force will not effect inertia if its force is zero?

Force does not affect inertia in general. Inertia can basically be identified with the mass.


Inertia will not be affected when this type of force is zero.?

Inertia will not be affected when "net" or "net force" is zero.


Is inertia balanced or unbalanced force?

-- "Inertia" is not a force. -- There is no such thing as a single balanced force or a single unbalanced force.


What is effect on inertia if force is doubled?

effect on inertia of a body if force is double?


Does force affect inertia?

Yes, force affects inertia. Inertia is the tendency of an object to resist changes in its velocity. When a force is applied to an object, it can change its acceleration and therefore its velocity, which in turn affects its inertia.


Why does inertia have net force?

Inertia itself does not have a net force. Inertia is the tendency of an object to resist changes in its motion. When a net force acts on an object, it can overcome this inertia and cause the object to accelerate or decelerate.


Is inertia a push or pull?

Neither. Inertia is not a force.


How can inertia be overcome?

Inertia can be overcome by applying an external force to an object. The greater the force applied, the quicker the object's inertia can be overcome. Once the external force is greater than the object's inertia, it will begin to move or change its speed/direction.


Which is force times time and which is inertia in motion?

Force times time is Impulse Inertia is mass


What is the relation of the force and inertia?

The greater the inertia, the greater is the force required to produce a constant acceleration.(F=ma). But in general, acceleration is not taken constant, in this case, there is no relation between force and inertia.
