If the rotational speed is measured in revolutions per unit of time, the linear speed and distance are increased proportionately by 2π in the above derivation to give:

If torque is in Newton-metres and rotational speed in revolutions per second, the above equation gives power in Newton-metres per second, or Watts.

If Imperial units are used, and if torque is in pounds-force feet and rotational speed in revolutions per minute, the above equation gives power in foot pounds-force per minute.

If other effects were ignored, tidal acceleration would continue until the rotational period of the Earth matched the orbital period of the Moon.

If that line of force is above the center of the contact points, this creates a moment or torque rotational force, causing the firearm to rotate and the muzzle end to rise upwards.

If the person in the chair pulls the weights towards them, they are doing work and their rotational kinetic energy increases.

If the engine is running at a constant speed, the rotational speed of each driving wheel can vary, but the sum ( or average ) of the two wheels ' speeds can not change.

If you grip the imaginary axis of rotation of the rotational force so that your fingers point in the direction of the force, then the extended thumb points in the direction of the torque vector.

If, however, the primary is tidally locked with the satellite, the rotational period will coincide with the 9. 7-day orbital period of Vanth.

If there is e. g. rotational symmetry with respect to an angle of 100 °, then also with respect to one of 20 °, the greatest common divisor of 100 ° and 360 °.

If one considers an isolated particle circling in the upper cylindrical component of the cyclone at a rotational radius of from the cyclone's central axis, the particle is therefore subjected to centrifugal, drag and buoyant forces.

If the tires are unidirectional, the rotation can only be rotated front to back on the same side of the vehicle to preserve the rotational direction of the tires.

If the central star's galactic orbit is eccentric ( elliptic or hyperbolic ), it will pass through some spiral arms, but if the orbit is a near perfect circle and the orbital velocity equals the " rotational " velocity of the spiral arms, the star will drift into a spiral arm region only gradually — if at all.

If it is well designed, a contra-rotating propeller will have no rotational air flow, pushing a maximum amount of air uniformly through the propeller disk, resulting in high performance and low induced energy loss.

If the same rotating object is viewed at 61 flashes per second, each flash will illuminate it at a slightly earlier part of its rotational cycle.

If back-up and rotational costumes are to be taken into account, the total costume count grows to around 450 costumes with 284 rotations.

If permitted, a 3-wheeler design will have 25 % less rotational inertia than a 4-wheeler, all else being equal.

If the rigid body has rotational symmetry not all orientations are distinguishable, except by observing how the orientation evolves in time from a known starting orientation.

If the blow falls above the CP ( center of percussion ) the movement of the CoG will cause the U-bolt to move away from the blow since the effect of the translational acceleration will outweigh the effect of the rotational acceleration.

If the blow falls below the CP the opposite will occur, rotational acceleration will outweigh translational acceleration and the U-bolt will move towards the blow.

If one eigenvalue is negative ( i. e., an imaginary frequency ), then the stationary point is a transition structure.

If measured instead per unit wavelength, using Wien's law, the peak is at 1. 06 mm corresponding to a frequency of 283 GHz.

If frequency-hopping is avoided, each base station can provide up to 120 channels in the DECT spectrum before frequency reuse.

If the two input signals are both sinusoids of specified frequencies f < sub > 1 </ sub > and f < sub > 2 </ sub >, then the output of the mixer will contain two new sinsoids that have the sum f < sub > 1 </ sub > + f < sub > 2 </ sub > frequency and the difference frequency absolute value | f < sub > 1 </ sub >-f < sub > 2 </ sub >|.

If the two signals are close together in frequency the heterodyne is low enough to be measured by a frequency counter.

If the baseband data signal ( the message ) to be transmitted is and the sinusoidal carrier is, where f < sub > c </ sub > is the carrier's base frequency and A < sub > c </ sub > is the carrier's amplitude, the modulator combines the carrier with the baseband data signal to get the transmitted signal:

If the frequency deviation is held constant and the modulation frequency increased, the spacing between spectra increases.

If the wavepacket has a relatively large frequency spread, or if the dispersion has sharp variations ( such as due to a resonance ), or if the packet travels over very long distances, this assumption is not valid.

If the length of the intervals on the x-axis are all 1, then a histogram is identical to a relative frequency plot.

If F is the only force acting on the system, the system is called a simple harmonic oscillator, and it undergoes simple harmonic motion: sinusoidal oscillations about the equilibrium point, with a constant amplitude and a constant frequency ( which does not depend on the amplitude ).

If a crest of a wave meets a crest of another wave of the same frequency at the same point, then the magnitude of the displacement is the sum of the individual magnitudes – this is constructive interference.

If the pump waves are of frequency ω < sub > 1 </ sub >

If two waves of the same wavelength and frequency are in phase, both the wave crests and wave troughs align.

If surviving Linear B clay tablets can be trusted, the name po-se-da-wo-ne (" Poseidon ") occurs with greater frequency than does di-u-ja (" Zeus ").

If light ( photons ) of frequency ν < sub > 12 </ sub > pass through the group of atoms, there is a possibility of the light being absorbed by atoms which are in the ground state, which will cause them to be excited to the higher energy state.

If an atom is already in the excited state, it may be perturbed by the passage of a photon that has a frequency ν < sub > 21 </ sub > corresponding to the energy gap ΔE of the excited state to ground state transition.

If we now subject the atoms to light of a frequency, the process of optical absorption will excite the atoms from the ground state to level 3.

If the object is moving either toward or away from the transmitter, there is a slight equivalent change in the frequency of the radio waves, caused by the Doppler effect.

If λ represents wavelength and f represents frequency ( note, λf = c where c is the speed of light ), then z is defined by the equations:

If an object moves with angular velocity ω around a circle of radius r centered at the origin of the x-y plane, then its motion along each coordinate is simple harmonic motion with amplitude r and angular frequency ω.

If the BFO frequency is off, the output signal will be frequency-shifted ( up or down ), making speech sound strange and " Donald Duck "- like, or unintelligible.

If is off by a small amount, then the beat frequency is not exactly, which can lead to the speech distortion mentioned earlier.
