# Trajectory of an Object in the Air

## Move the sliders to change the quadratic.

A quadratic equation can represent the trajectory of an object thrown in the air. A trajectory is the path of an object while it is in the air, ending when it hits the ground or intended target.
Point A gives the starting height of the object the millisecond it is released. The value of point A is the starting height.
Point B is the vertex of the quadratic. Point B gives the maximum height of the object in the air. The value of point B is the maximum height.
Point C is one of the roots of the quadratic. Point C gives the maximum horizontal distance of the object. The value of point C is the total distance the object was thrown. When point C is on the -axis, it is considered ground level.
Move sliders a, b or c.
Slider a is the coefficient in the term .
Slider b is the coefficient in the term .
Slider c is the constant term (also the coefficient in the term ).
