Inertia Demonstration

In this video there are two eggs that are being spun. One of the eggs is raw and the other is hardboiled. The hardboiled egg spins easily and smoothly while the raw egg is more bumpy because of the yolk inside. When the raw egg is touched while spinning it continues to spin, whereas the hardboiled egg stops completely. The raw egg continues to spin because the yolk inside never stopped moving or had any outside force acting upon it. This is a clear demonstration of inertia and Newton's first law which states an object in motion tends to stay in motion unless acted upon by and outside force. Although the egg was acted upon by and outside force, the yolk inside was not. The yolk caused the egg to continue spinning because of inertia. This video was helpful to understand this concept because it shows in a simple way how an object will continue moving unless it is directly acted upon by an outside force. This video made this concept helped me to understand that there could be an object inside of another object that causes it to keep moving.
