The Parabola Formula Calculator computes the y-coordinate value of a parabola given the x-coordinate value and the parabola constants (a, b and c) to create the equation y = a•x²+b•x+c.
INSTRUCTIONS: Enter the following:
Parabolic Value (y): The calculator returns the value for y.
The Math / Science
The formula for a parabola is
y = a•x²+b•x+c
One of the most common representations of a parabola in nature is an object moving in the gravitational field of a massive body, such as the projectile motion of a body affected by the Earth's gravity. The figure shows the parabolic trajectory typifying a projectile that is affected solely by gravity, g.
