Is it possible for a train to have less momentum than a squirrel?

Momentum is a measure of the force that a moving object has (due to its movement).
It is in direct proportion to both the object's mass and velocity. This means a higher mass, or a higher velocity means a higher momentum.
Momentum = mass * velocity (p = mv)
The mass of a train is vastly more than that of a squirrel.
Therefore the only time that a train would have less momentum is when it was not moving, compared to a squirrel that was moving. As soon as a train moves its momentum will be greater.
(You can think of it this way: you could overcome the force of a moving squirrel with your hand, but there is no way you could stop a train this way no matter how slowly it was moving.)

What happens to momentum when the mass decreases?
Less mass means less momentum. Momentum also depends on the velocity.
If velocity decreases then does its momentum?
Momentum is the product of mass times velocity. With less velocity, there will be less momentum. (An object's mass will usually not change.)
How is momentum increased?
With less inertia.
Would it be possible to build a train track that floats on water?
Sure, make the train tracks from materials that (in total) are lighter (less dense) than water. Presumably you want the train tracks to support a train as well; in that case, the weight of a certain piece of train tracks, plus the total weight of the train, should be less than the weight of the water displaced by the train tracks.
Why is momentum considered a very important quantity?
it takes less energy to maintain momentum than to acheive it.
Is it possible for an object to have more kinetic energy but less momentum?
yes,it is possible

What is meant when someone says that an athletic team has a lot of momentum or less its momentum?
More momentum would mean that the team has recently won several games or matches, and opposite for less momentum.
If you drop a suitcase out of a car what happens to the cars momentum?
If you drop a suitcase out of a moving car, the momentum of the car will decrease as there will be less mass, therefore less momentum. :)

How long can a Harris Antelope Squirrel live?
the lifespan of a harris antelope squirrel is just less than a year
Why AM waves transfer less momentum on striking an object?
Less than what? Please clarify.
What makes the car with less momentum does it better so it Requires acceleration?
you would have to be with less momentum better so acceleration isn't required. It would be the flux capacitor. without a doubt.
Does a 1-kg ball have less momentum or same momentum as a 10-kg ball?
Momentum is mass x velocity, so it would also depend on each ball's velocity.
