angular acceleration

angular acceleration

1 7.1
A measure of how fast an object's turning speed changes
  • noun
  • /ˈæŋɡjələr ˌækəˈlɛrəˌteɪʃən/
  • Specialized
translation icon : aceleración angular
  • The engineer measured the angular acceleration of the rotating wheel to ensure proper functioning.
  • angular acceleration of prosthesis
  • angular acceleration of the head

So torque about the center of mass equals moment of inertia about the center of mass times the angular acceleration.

Examples

  • During the experiment, the scientist recorded the angular acceleration of the pendulum as it swung back and forth.

  • For example, if you focus on problems where the body is has a constant angular acceleration alpha, what can you say?

  • The principal objective measurements were angular acceleration of the prosthesis and forward velocity of the body.

    Academic text (1991)

  • In Figure 4, the mean angular acceleration of the elbow and wrist joints is presented for all the trials and subjects at each seating position.

    Academic text (1992)

  • The angular acceleration curves of the elbow and wrist further stress the less abrupt change in the motion for the Backward-Low position.

    Academic text (1992)

  • The angular acceleration of the prosthesis at the beginning of the support phase was characterized mathematically as a damped oscillatory wave.

    Academic text (1991)

  • Injury criteria and angular acceleration of the head decrease slightly with moving the anchor point outboard, since less force is applied by the shoulder restraint in this scenario.

    Academic text (1996)

  • Decreases occurring in the head's linear and angular acceleration when the anchor point is moved rearward are significant and could represent a difference in the severity of an injury in such a crash.

    Academic text (1996)

  • The paired accelerometers, spaced 10 cm apart, provided differential signals to register angular accelerations calibrated in radians per second squared.

    Academic text (1991)

  • The calculation of angular acceleration is crucial for determining how quickly an object speeds up or slows down while rotating.

Morphology

angular + acceleration

The noun is a straightforward compositional combination: 'acceleration' (change in velocity) modified by 'angular' (relating to rotation), so the meaning — change in angular/rotational velocity over time — follows directly from the constituents. This adjective+noun technical pattern is cross-linguistically common (e.g., Spanish 'aceleración angular'), making it transparent to a learner who knows both words.

Etymology

Angular acceleration describes how quickly an object's turning speed changes. Think of a wheel: angular refers to the turning part and acceleration means a change in 'speed', so the term says how fast the wheel's 'spin' gets faster or slower.
