velocity decrease and at last it becomes zero.
The terminal velocity of a bullet is the maximum speed it can reach when falling through the air. This speed varies depending on the size and weight of the bullet. When a bullet reaches its terminal velocity, it will no longer accelerate and will fall at a constant speed. The terminal velocity of a bullet can affect its trajectory and impact force in several ways. A higher terminal velocity means the bullet will hit the target with more force, potentially causing more damage. Additionally, the trajectory of the bullet may be affected by air resistance at higher speeds, causing it to deviate from its intended path. Overall, the terminal velocity of a bullet plays a significant role in determining its impact on a target.
To reduce the velocity of a bullet in air, you can increase the drag force acting on the bullet by using a heavier or more aerodynamically shaped bullet, or by increasing the air density (e.g., shooting at higher altitudes). Additionally, you can decrease the initial muzzle velocity of the bullet by using a lower-powered cartridge or firearm.
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.
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.
That would depend on what you consider "large".The size of an object's momentum = (its mass) x (its speed).So, more mass and more speed result in more momentum.
No, momentum is determined by both mass and velocity. Even though a bullet can have a very high velocity, the mass of a huge truck is much greater, resulting in greater momentum.
A bullet with less grain (i.e., lighter weight) generally experiences more drop over a given distance compared to a heavier bullet, assuming both are fired at the same velocity. This is because lighter bullets are more affected by gravity and air resistance, causing them to lose velocity more quickly and drop more. However, other factors like ballistic design and environmental conditions can also influence the bullet's trajectory.
To a point, the velocity of the bullet will increase. However, at some point, the gasses driving the bullet have maxed out, and beyond that point, the bullet will begin to slow from friction with the barrel. For a .22 LR cartridge, that length is about 12 inches. Larger cartridges have a greater "Max velocity" length, but there is a point of no more gain, and the start of loss of velocity.

The only time that a car will stop a bullet is if you are in Hollywood, or have an armour-plated vehicle. A cow interposing itself between the bullet and yourself would reduce it velocity significantly more.
Impossible to answer without more info. Must have the bullet weight, barrel length, and muzzle velocity.
