Why does a speeding bullet and a fact moving train have so much force?
A speeding bullet and a fast-moving train have a lot of force because of their momentum. Momentum is the product of mass and velocity, so the greater the speed and mass of an object, the more force it has. In the case of a bullet or a train, their high velocity and mass result in a significant amount of force when they collide with another object.
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.)
Why does a moving car and train at the same speed not have the same kinetic energy?
While the car and train may be moving at the same speed, their kinetic energies can be different because kinetic energy depends on both the mass and velocity of an object. The train typically has a much larger mass than a car, so even if they are both moving at the same speed, the train will have a greater kinetic energy due to its higher mass.
Why when a ball thrown vertically upwards by a man in a moving train comes back to his hand?
that depends on 3 factors, how big is the circle, how fast is the train, and how high is the ball thrown also it is to be considered that u are assuming the natural (actual) conditions like the air thrust is present or hypothetical conditions that there is no air thrust. Under all ideal conditions i.e. no air thrust etc. the ball will move tangentially to the path of the circle the train is traversing.
If you jump in a moving train will you then end up further back in the train?
No, you will continue to move at the same speed as the train, so you will not end up further back in the train. Your position relative to the train will remain the same.

Why does a speeding bullet and a moving train have so much force?
Each of those items has large momentum and kinetic energy ... the bullet because of its high speed, and the train on account of its large mass.

How do you interpret a reference point?
something that stay at the same velocity...or dumbing it down :) is what an object is moving relative to something else.. so if there is a train and a girl watching the train the girl is a reference point because the train is moving relative of it
If you jump in a moving train will you then end up further back in the train?
No, you will continue to move at the same speed as the train, so you will not end up further back in the train. Your position relative to the train will remain the same.
How do you apply the concept of momentum to compare the mass and velocity of a slow moving train and of a high-speed bullet?
The momentum of an object is the product of its mass and velocity. In the case of a slow moving train and a high-speed bullet, the bullet would have a higher momentum due to its higher velocity even if its mass is smaller. This is because momentum is more affected by velocity than by mass.
Is it possible for a car moving with a consonant velocity to have forces acting on it.describe?
Yes, frictional forces such as air, tires against the ground, gravity pulling the car down, force of engine moving car forward. The positive force of the engine turning the drive train and the wheels is equaled by the frictional forces; so overall forces balance out.
What is the upward force on a moving object with a lift at a rate of 17m per s?
If the object is moving at a constant speed, the net force on it is 0. So the upward force would have to be equal to the downward force (namely the weight of the object).
What do you think has more momentum a moving car or a moving train?
A moving train typically has more momentum than a moving car, due to its greater mass and often higher speed. Momentum is determined by both an object's velocity and mass, so the larger mass of a train contributes to its greater momentum compared to a car.
