The parabola is a member of the conic sections, along with hyperbola and ellipse. The St. Louis arch, the McDONALD arches are examples of parabolae in the physical world. The parabola can be seen on saturday and sundays when you sit to watch a football game. When a quarterback throws a fourty yard pass the projectile motion is that of a parabola. There is the ascension trajectory when he releases the ball, there is the peak at the very top where the speed of the object is near or at zero, and then there is the descension where the ball is picking up speed on the downward trajectory. The head lights on car have a parabolic shape, with one particular entity, the focus,. It is placed in the center of the parabola and it diffracts light rays through it and the passing light hits the base of the parabola then bounces of outward. It almost seems that the focus polarizes the light rays because as the light ray passes through the focus the path of the light is physically altered. Satellite dishes are made into the shape of parabolas because it allows for information to be bounce of it and sent into a particular trajectory. The parabola is pervasive in our everyday world, it is not just a concept in a math class.
