מחשבון מהירות
Solve v = d / t for velocity, distance or time — enter any two values and get the third.
מחשבון תאוצה
Find acceleration from the change in velocity over time with a = (v − u) / t.
מחשבון כוח
Apply Newton's second law F = m × a to solve for force, mass or acceleration.
מחשבון אנרגיה קינטית
Compute kinetic energy in joules with KE = ½ m v² from mass and speed.
מחשבון אנרגיה פוטנציאלית
Find gravitational potential energy with PE = m g h using standard gravity.
מחשבון צפיפות
Solve ρ = m / V for density, mass or volume from any two known values.
Ohm's Law Calculator
Solve V = I × R for voltage, current or resistance, with electrical power included.
מחשבון הספק חשמלי
Work out electrical power in watts with P = V × I and the energy used per hour in kWh.
מחשבון נפילה חופשית
Get the fall time and impact velocity of an object dropped from a height, ignoring air resistance.
מחשבון אורך גל
Convert frequency to wavelength with λ = v / f — defaults to the speed of light for radio and light waves.
