How a bullet work

A bullet is a small, cylindrical piece of metal that is fired from a firearm. When a bullet is fired, the explosion from the gunpowder propels it forward through the barrel of the firearm. The bullet's velocity and energy are determined by the weight and shape of the bullet, the type of gunpowder used, and the pressure generated by the explosion. When a bullet hits its target, its kinetic energy is transferred, causing damage to the target. The speed and mass of the bullet, combined with its shape, determine the extent of the damage inflicted.
