Final answer:
Military rifles have a mechanism to reduce recoil forces by allowing an internal part to recoil over a larger distance, which reduces the average force needed to stop it.
Step-by-step explanation:
In military rifles, there is a mechanism in place to reduce the recoil forces experienced by the person firing the gun. This mechanism involves an internal part that recoils over a large distance and is stopped by damping mechanisms within the gun.
The larger distance over which the internal part recoils help to reduce the average force needed to stop it. This is because stopping the internal part over a larger distance allows for a longer duration of time over which the force is applied, effectively reducing the overall force required to stop the recoil.
