How To Use

How to use this calculator

Start with your values, or try a preset.

Step 1

Enter Initial Velocity (m/s) and Time of Fall (seconds) in the units shown.

Step 2

Read Acceleration Due to Gravity (m/s²), Distance Fallen (meters), and Final Velocity (m/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.
