Among a Bowling ball, a planet, a car, and a train, the planet has the greatest inertia. Inertia depends on an object's mass, and planets have significantly more mass than the other items listed, meaning they resist changes to their motion more than the others do. While a bowling ball is heavy, it pales in comparison to the mass of a planet.
The train has the greatest inertia of rest or of motion among the vehicles listed. Trains are extremely massive and have a lot of inertia due to their weight and speed, making them harder to start, stop, or change direction.
Inertia is related to speed and mass; a train is both faster and more massive than a car.
A train has more inertia than a car because inertia depends on mass, and trains are typically much heavier than cars. Even if both the train and car were moving at the same velocity, the train's higher mass means that it requires more force to change its speed or direction, giving it greater inertia.

They were train on the planet, Kamino.
A train has greater inertia than a car. This is because the train's mass is larger, so it requires more force to accelerate or decelerate compared to a car due to its greater resistance to changes in motion.
A train would have more inertia than a car because inertia is determined by an object's mass, and trains typically have much greater mass than cars. Inertia is the tendency of an object to resist changes in its state of motion, so an object with more mass (like a train) will have more inertia compared to an object with less mass (like a car).
Take the 4 or 5 downtown train in Manhattan .
If the train is travelling at a constant speed the pen is also travelling at a constant speed and will drop straight down but if the train accelerates or brakes after the pen is dropped it will not drop straight down. This is because it has it's own inertia, it still drops straight but everything else has changed their inertia so it just looks as if the pen is different.
If the train appeared to be moving while it was at rest, it is because of inertia.
A massive object has greater inertia. It requires more force to slow it down or change it's course. Example: It takes much more force to stop a train than it does to stop a car, only because the train has much greater mass.
