horizontal motion with resistance
... low speeds. In the motion through a fluid, the resistive force FR v is often called the viscous drag and it arises from the cohesive forces between the layers of the fluid. The S.I. units for the constant are N.m-1.s-1 or kg.s-1. Model (2) for quadratic resistance is more applicable for high ...

Mass on a Spring: Oscillations
... Professor William “Wild Bill” Deering once observed that “all the world's a harmonic oscillator”, meaning that a great many physical processes can be explained in terms of one simple model: the harmonic oscillator. Over the next two labs, we'll see why that's true. To begin, we'll consider a linear ...
