The property that makes it hard to stop a moving train is its momentum. Momentum is a vector quantity that depends on both the train's mass and velocity. The higher the train's mass and speed, the greater its momentum and the more force is needed to stop it.
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.)
Momentum is the product of an object's mass and velocity. A high-speed bullet has more momentum than a slow moving train because the bullet has a smaller mass but much higher velocity. This means the bullet can have more impact and be harder to stop compared to the train, even though the train has more mass.
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.
A fast-moving car has more momentum than a slow-moving car because momentum is directly proportional to an object's velocity. The momentum of an object is the product of its mass and velocity, so the faster the object is moving, the greater its momentum.

The Roller-skate Momentum = (mass) multiplied by (speed) . Anything moving has more momentum than anything that's not moving. The thing that's not moving has zero speed, so it also has zero momentum.
The momentum of an object is the product of both the mass and velocity of the object. A train moving at ten miles per hour will have more momentum than a ball moving at ten miles per hour, because the train is much heavier and larger.
A fast-moving car has more momentum than a slow-moving car because momentum is directly proportional to an object's velocity. The momentum of an object is the product of its mass and velocity, so the faster the object is moving, the greater its momentum.

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.
Momentum (p) is defined as mass (m) times velocity (v). p = m*v Therefore, if you increase velocity, you also increase momentum. You can easily observe this by noting that it takes more force to slow down a faster moving object than a slower moving object.
A large mass moving slowly would have more momentum than a small mass moving slowly because momentum is a product of mass and velocity. Even if both masses are moving at the same speed, the larger mass would still have more momentum due to its greater mass.
A bullet fired from a gun has more momentum than a train at rest because momentum is the product of an object's mass and velocity. The bullet, despite being smaller in mass compared to the train, can have a significantly higher velocity, resulting in a greater momentum.
