속도 계산기

Distance (m) Time (s) Velocity (m/s) — leave blank to solve

Solve v = d / t for velocity, distance or time — enter any two values and get the third.

Initial velocity u (m/s) Final velocity v (m/s) Time (s)

Find acceleration from the change in velocity over time with a = (v − u) / t.

Mass (kg) Acceleration (m/s²) Force (N) — leave blank to solve

Apply Newton's second law F = m × a to solve for force, mass or acceleration.

Mass (kg) Velocity (m/s)

Compute kinetic energy in joules with KE = ½ m v² from mass and speed.

Mass (kg) Height (m)

Find gravitational potential energy with PE = m g h using standard gravity.

Mass (kg) Volume (m³) Density (kg/m³) — leave blank to solve

Solve ρ = m / V for density, mass or volume from any two known values.

Voltage V (V) Current I (A) Resistance R (Ω)

Solve V = I × R for voltage, current or resistance, with electrical power included.

Voltage (V) Current (A)

Work out electrical power in watts with P = V × I and the energy used per hour in kWh.

Drop height (m) or Fall time (s)

Get the fall time and impact velocity of an object dropped from a height, ignoring air resistance.

Frequency (Hz) Wave speed (m/s) — blank = speed of light

Convert frequency to wavelength with λ = v / f — defaults to the speed of light for radio and light waves.
