It depends on the bone.
Not all bones are the same. Not only does it depend on the thickness of the bone, but also on the shape. For example, Hamate fracture (aka. wrist-bone-below-the-pinky fracture) is fairly common among Baseball players, because it has an outward area shaped like a small hook, and it is near the surface of the palm.
On the other hand, the Femur (aka. Thigh bone) is harder than concrete.
Then there are factors like age, previous bone problems, etc.
a break in the bone is the same as a fracture.
you can't break your penis as it is not a bone it is just a muscle so you cant break it.
It is a bone cell. Osteo=bone+cyte=cell.Osteoblast build bone. Osteo=bone+blast=build.Osteoclasts break bone. -clast=break
It's not the speed, it's a specific pressure exerted to a point of area of bone mass and measured in pounds per square inch creating variable breaking points due to stength and the resiliency tolerance of the bone.
A straight break across the bone is called a transverse fracture.
You cant break your ear as it is not a bone and it is simply fat and tissue :)
The bone that you try not to break is the xiphoid process.
