[1] The Magnus effect is named after Heinrich Gustav Magnus , the German physicist who investigated it. The force on a rotating cylinder is an example of Kutta–Joukowski lift, [ 2 ] named after Martin Kutta and Nikolay Zhukovsky (or Joukowski), mathematicians who contributed to the knowledge of how lift is generated in a fluid flow.
In mechanics and physics, shock is a sudden acceleration caused, for example, by impact, drop, kick, earthquake, or explosion. Shock is a transient physical excitation. Shock describes matter subject to extreme rates of force with respect to time. Shock is a vector that has units of an acceleration (rate of change of velocity).
A diamond plate texture rendered close-up using physically based rendering principles. Microfacet abrasions cover the material, giving it a rough, realistic look even though the material is a metal. Specular highlights are high and realistically modeled at the appropriate edge of the tread using a normal map.
In cosmology, a texture is a type of topological defect in the order parameter (typically a scalar field) of a field theory featuring spontaneous symmetry breaking. [1] [2] [3] They are not as localized as the other defects, and are unstable. No textures have been definitively confirmed as having been detected, but their existence is compatible ...
Algodoo (/ ˌ æ l ɡ ə ˈ d uː /) is a physics-based 2D freeware sandbox from Algoryx Simulation AB (known simply as Algoryx) as the successor to the popular physics application Phun. It was released on September 1, 2009 and is presented as a learning tool, an open-ended computer game, an animation tool, and an engineering tool.
The first equation shows that, after one second, an object will have fallen a distance of 1/2 × 9.8 × 1 2 = 4.9 m. After two seconds it will have fallen 1/2 × 9.8 × 2 2 = 19.6 m; and so on. On the other hand, the penultimate equation becomes grossly inaccurate at great distances.
A droplet with a diameter of 3 mm has a terminal velocity of approximately 8 m/s. [5] Drops smaller than 1 mm in diameter will attain 95% of their terminal velocity within 2 m. But above this size the distance to get to terminal velocity increases sharply. An example is a drop with a diameter of 2 mm that may achieve this at 5.6 m. [5]
The minimum contact time for a low deformation drop (We << 1) is approximated by the lowest-order oscillation period for a spherical drop., [8] giving the characteristic time a prefactor of approximately 2.2. [9] For large-deformation drops (We > 1), similar contact times are seen even though dynamics of impact are different, as discussed below ...
