Projectile Motion Calculator

Trajectory of a projectile. Calculates height, distance and time of flight. Physical Sciences index Classical mechanics index: The trajectory of a perfect projectile (over a flat surface, ignoring air resistance) describes a parabola.

This calculator helps to determine parameters of projection, or ballistic motion. The parameters of projection, as shown on picture, are:distance,maximum height,flight duration,initial angle,initial velocity.The main equations are:These formulae are produced from equations of accelerated motion with the assumption that there is no acceleration along x-axis and only gravity acceleration 'g' along y-axis.Calculator can find unknown parameters for any pair of known parameters.That is, it calculates the flight duration, maximum height and travel distance of the projection from the initial velocity and angle. Or it calculates the initial velocity, travel distance and flight duration of the projection from the initial angle and maximum height. Contra hard corps speed.

The only illegal combination of parameters is maximum height and flight duration. Given only these, it is impossible to find others.
