Inertia is the tendency of an object to resist any change in its motion.
Two objects with the same mass and same velocity will both have the same amount of inertia. However, if they have different velocities, they will have different amounts of inertia.
Consider two trains, one moving at 100 kilometers per hour, and the other moving at 120 kilometers per hour. If they both brake at the same time, the slower one will come to a stop sooner than the faster train, because the faster train has more inertia and can resist more friction than the slower train.
Lighter Objects have LESS "inertia". Mass is physical manifestation of inertia. Mass is weight so the more mass the more potential inertia to over-come -- either to make an object move or to stop an object once it is moving. So, if a meteorite weighing 1 gram hits a space station weighing 1,000 tons the likelihood of the object causing damage is proportional to the speed of the meteorite; but if the meteorite weighs 1,000 tons (same as space station) the sheer mass alone would cause damage (regardless of movement because any movement would be too much.)
The distribution of mass within the object can affect its inertia. An object with the mass distributed further from its axis of rotation will have higher inertia compared to an object with the same mass but a more compact distribution. Additionally, the shape and size of the object can also impact its inertia.
Yes, different liquids have different refractive indices, which can cause the amount of refraction to change when light passes through them. This can lead to distortions in the appearance and position of objects as seen through the liquid.
The study of motion is called kinetics. It involves analyzing the forces and interactions that cause objects to move.
Inertia itself does not cause objects in motion to come to rest. Objects in motion tend to continue moving in a straight line unless acted upon by an external force, in accordance with Newton's first law of motion. When external forces such as friction or air resistance act upon an object, they provide a force in the opposite direction of the object's motion, eventually causing it to come to rest.
Different velocities is what causes objects to have the same mass and different amounts of inertia. This can be written in a formula.
If the objects have different velocities they will have different inertia.

Fluid inertia refers to the resistance of a fluid to changes in its motion. When an object moves through a liquid medium, the fluid's inertia can cause it to resist changes in direction or speed. This can affect the movement of the object by making it harder to accelerate or decelerate, and can also cause the object to experience drag or turbulence as it moves through the fluid.
No.
Inertia itself is not harmful; it is a property of matter to resist changes in motion. However, inertia can lead to issues if not properly managed, such as in situations where quick changes in motion are needed, like during car accidents or sudden movements that can cause injury. It is important to consider and account for inertia when designing systems or handling objects to prevent accidents or damage.
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...
A force can cause an object to move if the amount of the force in the direction of movement is larger than the Frictional force of the object against the object on which it rests, and can overcome its Inertia.
