Particles Velocity Calculator

Find average velocity from displacement and time.

Instructions

Enter particle displacement and the elapsed time. The calculator returns average velocity magnitude and sign (direction by sign).

Formula

v = Δx / Δt

About Particle Velocity

Average velocity is displacement over time. For instantaneous velocity, calculus (dv/dt) is required.

Common Questions

Is this instantaneous velocity?

No, it is average velocity over the interval. Instantaneous velocity requires limits.

What if the particle reverses direction?

Displacement can be smaller than path length; this computes vector average, not speed.
