Why would a train have more inertia than a car if they both had the same velocity they both they both?

While they may both have the same speed, the train WEIGHS thousands of times what the car weighs.

What would cause objects that have the same mass to have different amount of inertia?
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.
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.
Does a 1 kilogram ball or a 10 kilogram ball have more momentum?
Inertia is directly proportional to mass. Unless you mean rotational inertia, in which case it depends on the shape, but for two objects of the same shape (and mass distribution), the more massive always has higher inertia.
Are you saying inertia is a source of gravity?
Gravity is related to masses. Inertia is simply another effect of masses. I would say that the mass is the source, both for gravity and for inertia. The basic unit, however, is the mass.Gravity is related to masses. Inertia is simply another effect of masses. I would say that the mass is the source, both for gravity and for inertia.

When you want to change an object's velocity you have to overcome?
1. The Object's INERTIA. 2. The Object's MOMENTUM. Both of these factors are directly dependent on the Object's MASS.
An objects resistance to change in motion?
Inertia. Inertia applies to both increases and decreases in velocity.

It is harder to stop a rolling bowling ball than a rolling ping pong ball when both are rolling at the same velocity. this is an example of?
It is an example of inertia.

Why does momentum have a direction?
Because momentum is mass X velocity. Velocity has direction, otherwise it is speed.
What forces act upon a falling feather?
The obvious is gravity. Wind creates both lift and rotation, both of which create inertia. If the feather tilts, it will also be subject to acceleration and/or velocity loss.
If a train is stopped suddenly then it's acceleration will be zero or it's velocity will be zero?
As it slows it's acceleration will be negative, deceleration is negative acceleration. During the slow down the velocity will drop. Once at rest both acceleration and velocity will be zero.
What will happen when a stone is thrown from a moving train?
Throwing a stone from a moving train involves the same type of calculations as throwing a stone from a stationary platform. The difference is that you now consider the added horizontal velocity imparted by the moving train. If you throw forward, the train's velocity is added to your contribution to the stone. If you throw backward, the train's velocity is subtracted from your contribution to the stone. If you throw sideways, the train's velocity does not alter your contribution to the stone. Whether any of this matters or not depends on friction due to the different air velocities encountered by the stone. Vertical velocity is relatively unchanged by the train's contribution. The stone will still go up (if you include an upward vector in your throw) and it will still go down. The end result is that the stone will hit the ground at some point. That point will be relatively the same in both cases, except for the minor difference due to air velocity.
Can particle with constant velocity be accelerating?
No. Velocity implies both a magnitude and a direction.No. Velocity implies both a magnitude and a direction.No. Velocity implies both a magnitude and a direction.No. Velocity implies both a magnitude and a direction.
