As per Newton's law of motion, force is equivalent to the rate of change of momentum, and momentum is the product of mass and velocity. A bullet's mass is very high when it is fired. As a result, the momentum becomes high enough to penetrate through a thick object which, on being hit, changes the momentum of the bullet to a very small value.
This will be easily understood if you consider that when you gently place a very heavy object on the floor, the floor does not get damaged, but if you throw a much lighter stone at a higher speed, it may create a dent in the floor.
