What is a real-life example of a parabola?

Answer 1

Parabola: A plane curve produced by a point moving in such a way that its distance from a fixed point equals its distance from a fixed-line.

The standard equation of a regular parabola is $y^2=4ax$, where $a$ is the distance from the vertex to focus of the parabola.
