When a mechanic tries to remove a hex nut with a wrench, it is easier if the force is applied at the farthest end of the wrench handle. The lever arm…
![Rolling Without Slipping](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/14706.jpg)
People have observed the rolling motion without slipping ever since the invention of the wheel. For example, one can look at the interaction between…
![Rolling With Slipping](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/14707.jpg)
Rolling with slipping is a physical phenomenon that occurs when a rolling object experiences both rotational and linear motion but also experiences…
![Work-Energy Theorem for Rotational Motion](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/12713.jpg)
The work-energy theorem for rotational motion is analogous to the work-energy theorem in translational motion. It states that the net work done by an…
![Angular Momentum: Single Particle](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/12714.jpg)
Angular momentum is directed perpendicular to the plane of the rotation, and its magnitude depends on the choice of the origin. The perpendicular…
![Conservation of Angular Momentum](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/12716.jpg)
A system's total angular momentum remains constant if the net external torque acting on the system is zero. Considering a system that consists of…
![Conservation of Angular Momentum: Application](https://jovecdn2.ccindex.cn/files/media/science-education/science-education-thumbs/12717.jpg)
A system's total angular momentum remains constant if the net external torque acting on the system is zero. Examples of such systems include a…
![Uncoupling Coriolis Force and Rotating Buoyancy Effects on Full-Field Heat Transfer Properties of a Rotating Channel](https://jovecdn2.ccindex.cn/files/thumbs/57630_t.png)
An experimental method for exploring the heat transfer characteristics of an axially rotating channel is proposed. The governing flow parameters that…
![Fabricating van der Waals Heterostructures with Precise Rotational Alignment](https://jovecdn2.ccindex.cn/files/thumbs/59727_t.png)
In this work we describe a technique for creating new crystals (van der Waals heterostructures) by stacking distinct ultrathin layered 2D materials.…
