We use 3D printing to fabricate anisotropic particles in the shapes of jacks, crosses, tetrads, and triads, whose alignments and rotations in turbulent fluid flow can be measured from multiple simultaneous video images.

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Visual mental imagery refers to the ability to conjure images in one’s mind’s eye. This allows people to process visual material above and beyond the constraints of a current point-of-view; for example, a person could imagine, using their mind’s eye, how something might look in a different color, or what it would look like if it were made from a different material or rotated and seen from a different perspective. Mental imagery...

Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame. The absolute velocity of point B is determined by adding the absolute velocity of point A, the relative velocity of point B in the rotating frame, and the effects caused by the angular velocity within the rotating frame. Time differentiation is...

Source: Nicholas Timmons, Asantha Cooray, PhD, Department of Physics & Astronomy, School of Physical Sciences, University of California, Irvine, CA Inertia is the resistance of an object to being accelerated. In linear kinematics, this concept is directly related to the mass of an object. The more massive an object, the more force is required to accelerate that object. This is seen directly in Newton's second law, which states that force is equal to mass times acceleration. For rotation,...

Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame. However, to express the relative position of point B relative to point A, an additional frame of reference, denoted as x'y', is necessary. This additional frame not only translates but also rotates relative to the fixed frame, making it instrumental in...

The analysis combines angular displacement with elapsed time, so it describes both how far an object turns and how quickly that change occurs. A revolution-based result can be expressed in revolutions per second, while the same rotational behavior may be represented in radians per second. This provides a consistent basis for comparing different rotating systems.
Period and frequency describe repeating rotation from complementary perspectives. The period specifies the time associated with the motion’s cycle, whereas frequency characterizes how often the cycle occurs. Using either measure helps organize periodic observations and compare rotating objects whose motion may be reported through different time-based quantities.
Rotation Rate Analysis separates the turning of an object about its axis from motion along a circular path. Angular measures describe the overall rotation, while linear speed describes motion at a position on the object. Relating these perspectives is especially important for interpreting rigid-body motion and understanding how rotation produces movement through space.
A basic measurement records the angular displacement of an object and the time required for that change. The measured values are then used to determine the angular velocity, with the result reported in revolutions per second or radians per second. Repeated observations of periodic motion can also provide its period or frequency for comparison.
The method applies to many systems in which motion occurs around an axis, including wheels, turbines, motors, and laboratory apparatus. Comparing their measured rotation rates can help evaluate how their rotational motion differs. In laboratory work, the same approach supports systematic observations of rotating components during physics experiments.
In kinematics, rotation-rate measurements describe how rotational motion changes over time. In dynamics, they help characterize the behavior of rotating systems, while conservation-of-angular-momentum experiments use comparisons of rotational motion to examine how that quantity is maintained. This makes the analysis useful across several connected areas of physics rather than as an isolated measurement.
