Q:

How far can a bullet travel underwater?

A:

According to MythBusters, bullets from high-powered guns disintegrate in less than 3 feet underwater. Slower bullets, including those from pistols, travel for about 8 feet underwater. Bullets fired at an angle stop underwater at shorter ranges than those fired vertically into water.

Water is denser than air, making it more difficult for objects to move. Forces that result in forward movement are known as thrust. Drag slows movement by pulling against thrust. When thrust is greater than drag, forward movement results. In water, drag is greater than in air, resulting in more difficulty with forward movement. The movement of currents in water also affects the ability of objects and animals to move underwater.

  • Q:

    How far will bullets travel?

    A:

    The distance a bullet travels is entirely dependent on the gun from which it is fired. The muzzle velocity and maximum range of a specific weapon both need to be taken into account in order to calculate how far a bullet travels after being fired.

  • Q:

    What is the terminal velocity of a bullet?

    A:

    Terminal velocities of bullets vary by caliber, but can reach 300 to 700 feet per second. For example, a .30 caliber bullet's terminal velocity is 300 feet per second. If the bullet is shot at an angle and keeps its arc, it is more likely to reach terminal velocity.

  • Q:

    Can a bullet have the same momentum as a truck?

    A:

    A bullet can have the same momentum as a truck if it is moving fast enough. Momentum is defined in classical physics as the product of mass and velocity. A bullet has a fixed mass, so by sufficiently increasing the velocity it can achieve the momentum of a truck.

    How do bullet trains work?

    A:

    Bullet trains, also called maglev trains, operate with magnetic levitation technology developed by Japanese and German engineers. Japanese engineers refer to their method as electrodynamic suspension while German engineers refer to their method as electromagnetic suspension. Either way, magnets raise the trains above the track, which means there is no need for wheels.
