Calculadora de Densidade

Use the free online Calculadora de Densidade tool. Fast, private and easy to use — runs entirely in your browser. Part of our Calculadoras de Física collection.

Calculadora de Velocidade

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.

Calculadora de Aceleração

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.

Calculadora de Força

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.

Calculadora de Energia Cinética

Mass (kg) Velocity (m/s)

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

Calculadora de Energia Potencial

Mass (kg) Height (m)

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

Calculadora de Densidade

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.

Ohm's Law Calculator

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

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

Calculadora de Potência Elétrica

Voltage (V) Current (A)

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

Calculadora de Queda Livre

Drop height (m) or Fall time (s)

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

Calculadora de Comprimento de Onda

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.
