Projectile Motion Calculator

April 2020

Android app for solving common physics kinematics equations

Development

The app was written in Java, in Android Studio.

How it works

The app features two different modes of calculation. 1-dimensional motion and 2-dimensional motion.

1-D projectile motion is described by,

x_f = \frac{1}{2}at^2 + v_i t + x_i

2-D Motion is described by,

y_f = \frac{a}{2v_x^2}x^2 + \frac{v_y}{v_x} x + y_i

The app lets the user input known information and it solves for the missing variable. After obtaining and answer, the value can optionally be converted to a different set of units. This allows the solving of most kinematics problems such as time taken to hit the ground or angle required to hit a target.
