Kinematics Calculator

Use initial velocity, acceleration, and time or initial/final velocity and time to calculate displacement and related quantities.

Solve mode

Initial velocity (m/s)

Acceleration (m/s²)

Time (s)

—final velocity m/s

—acceleration m/s²

—displacement m

—average velocity m/s

—One-dimensional constant-acceleration model.

These are idealized classical-physics calculations. Real systems can differ because of air resistance, friction, deformation, measurement uncertainty, non-constant forces, or other effects not included in the selected model.
