Concussions are a direct result of Newton’s Laws of Motion. The bone of the skull itself is relatively strong, therefore it can handle large forces that give large to the skull, as described by of Motion. However, the brain is surrounded by cerebral-spinal fluid inside the skull and thus when the skull accelerates the brain tends to continue its original motion, ( of Motion). Aside from some slowing due to within the fluid, the brain will then strike the hard inside surface of the skull at nearly full and come to rest, or even bounce and change direction, over a very small time interval. This massive acceleration on the brain coincides with a force on the brain that is much greater than brain tissue can handle, causing a brain injury. In simple terms, just because the skull can handle an impact, that doesn’t mean the brain can.

the change in velocity per unit time, the slope of a velocity vs. time graph
the acceleration experienced by an object is equal to the net force on the object divided my the object's mass
an object's motion will not change unless it experiences a net force
a force applied by a fluid to any object moving with respect to the fluid, which acts opposite to the relative motion of the object relative to the fluid
distance traveled per unit time
