It is one of the difficult points of physics teaching to ask the static friction force of solving. 为解决静摩擦力难以判断的问题,提出了概念判断法、加速度判断法、综合分析法等方法。 更多例句>> 3) static frictional force 静摩擦力 1. A discussion is made of the work done by static friction...
Switch tonew thesaurus Noun1. static magnet- a magnet that retains its magnetism after being removed from a magnetic field permanent magnet magnet- (physics) a device that attracts iron and produces a magnetic field stud finder- a small permanent magnet in a metal container; when the magnet cl...
(See “Handbook of Chemistry and Physics” in the lab.) However, these tabulated values are only average values; actual values can vary widely because no two pieces of material are exactly alike. Experiment 1: Force of Kinetic Friction, Wood on Wood In the illustration above, a weighted ...
Tags Block Forces Friction Incline Physics Static Static friction In summary, we were dealing with a block on an incline that could be altered by changing the angle. We found that the critical angle at which the block just begins to slide can be used to write an equation for the coefficient...
In the context of physics, static refers to forces or objects at rest or in equilibrium, with no net force acting upon them. Dynamic relates to forces causing movement or change in objects. For instance, static friction prevents an object from moving, while dynamic friction occurs when an obj...
1)static friction静摩擦力 1.Judging the direction of thestatic frictionof rigid body in motion needs only the presupposition that the rigid is not influenced by thestatic friction,and then the reverse direction of the acceleration of the touch point on the rigid body opposite the contact surface...
We systematically investigated the waiting-time dependence of the maximum static friction force, Fs(tw), using the dynamics of driven vortices in a high-Tc superconductor as a model system. Fs(tw) was measured in La2 ? xSrxCuO4 thin films with different structures, sample sizes and pinning ...
Friction is one of the fundamental issues in physics, mechanics and material science with many practical applications. However, the understanding of macroscopic friction phenomena from microscopic aspect is still on the way. In this paper, molecular dynamics simulations are performed to investigate the ...
What does friction mean in physics? Does direction of friction matter in centripetal force equations? Why is friction like applied force but different from gravity? Why is frictional force a nonconservative force? When we have friction from rolling, is the friction vector always in the opposite ...
9. (Telecommunications) random hissing or crackling or a speckled picture caused by the interference of electrical disturbances in the reception of radio or television transmissions 10. (General Physics) electric sparks or crackling produced by friction [C16: from New Latin staticus, from Greek stati...
