Linear & Angular Velocity Calculator (v=ωr)

Favorite

Compute linear velocity via v = ω·r = 2πn·r/60: enter rotational speed and radius to get linear and angular velocity.

Key points

Linear & Angular Velocity Calculator (v=ωr): Compute linear velocity via v = ω·r = 2πn·r/60: enter rotational speed and radius to get linear and angular velocity. Formula: v = ω·r = 2π·n·r/60. Enter parameters on the DD-CAT IDE online tool page to get results instantly, with a calculation-model diagram that updates with the inputs. v = ωr: linear velocity equals angular velocity times radius; at the same speed, a larger radius gives higher linear velocity (grinding wheels, cutting tools, tires). ω = 2πn/60 (n in rpm): 1500 rpm ≈ 157 rad/s; linear velocity v = 2πnr/60.

Engineering notes

  • v = ωr: linear velocity equals angular velocity times radius; at the same speed, a larger radius gives higher linear velocity (grinding wheels, cutting tools, tires).
  • ω = 2πn/60 (n in rpm): 1500 rpm ≈ 157 rad/s; linear velocity v = 2πnr/60.
  • Engineering uses: checking motor shafts, pulleys, wheels and grinding-wheel surface speeds; high-speed rotors need centrifugal-stress and balance checks.
