... but if they are frequency-dependent, this condition becomes (ω)0 ≡ d(ω)/dω > 0 and (ωµ)0 ≡ d(ωµ)/dω > 0. This allows (ω) and µ(ω) to be negative at some frequencies, if they have strong frequency dependence. While strong frequency dependence of is common, most materials have µ ' 1 at optical fr ...

3.4 Newton`s Law of Inertia - Fort Thomas Independent Schools
... Is a force required to keep an object moving? Newton’s first law, usually called the law of inertia, is a restatement of Galileo’s idea that a force is not needed to keep an object moving. Galileo argued that only when friction is present is a force needed to keep an object moving. Galileo state ...

Finding the coefficient of friction used in a simulation
... Use the interactive physics software to simulate the classic Newton’s law experiments we attempt in class by simulating a 200 g mass to accelerate both itself and a 1.0 Kg mass. The larger mass should be placed on a level surface such that it drags along on the level surface. As it does, track the h ...
