Velocity Calculator

Physics
0.0(0)

Calculates velocity based on displacement and time, or using kinematic equations.

How To Use

How to use this calculator

Start with your values, or try a preset.

Step 1

Enter Displacement, Time, Initial Velocity, and Acceleration in the units shown.

Step 2

Read Final Velocity (Kinematic Equation) and Average Velocity (Displacement/Time) 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.

Constant Velocity

Displacement: 20 m; Time: 4 s; Initial Velocity: 0 m/s; Acceleration: 0 m/s²

Final Velocity (Kinematic Equation): 0 m/s; Average Velocity (Displacement/Time): 5 m/s

Accelerating Object

Displacement: 0 m; Time: 5 s; Initial Velocity: 0 m/s; Acceleration: 2 m/s²

Final Velocity (Kinematic Equation): 10 m/s; Average Velocity (Displacement/Time): 0 m/s

Decelerating Object

Displacement: 0 m; Time: 10 s; Initial Velocity: 10 m/s; Acceleration: -1 m/s²

Final Velocity (Kinematic Equation): 0 m/s; Average Velocity (Displacement/Time): 0 m/s
