Projectile Motion Calculator

0.0(0)

Calculates trajectory parameters (range, height, time of flight, velocity) for an object launched at an angle.

How To Use

How to use this calculator

Start with your values, or try a preset.

Step 1

Enter Initial Velocity (m/s), Launch Angle (degrees), and Gravity (m/s²) in the units shown.

Step 2

Read Horizontal Velocity (m/s), Max Height (m), Range (m), and Time of Flight (s) in the results panel. Results update as you change the inputs.

Step 3

Choose a preset to load an example, then adjust the values for your situation.
