7.2 Kinetic Energy and the Work-Energy Theorem

WebMar 5, 2024 · Energy is consumed because the object gives kinetic energy to the fluid (say, water or air); viscosity, as we will model in Section 6.4.4, then turns this energy into heat. The kinetic energy depends on the mass of the fluid and on the speed it is given. The mass of fluid in the tube is \(\rho A_{cs} d\), where \(\rho\) is the fluid density. WebWhen molecules rebound from a wall in a container, the change in momentum gives rise to a force exerted by the particle on the wall; ... Keep in mind this particular equation for kinetic energy is only for one molecule in the gas. If you want to find the kinetic energy for all the molecules, remember to multiply by $\boldsymbol{N}$, the total ... WebSep 12, 2024 · The work-energy theorem says that this equals the change in kinetic energy: − mg(yf − yi) = 1 2(v2 f − v2 i). Using a right triangle, we can see that (yf − yi) = (sf − s − i)sinθ, so the result for the final speed is the same. What is gained by using the work-energy theorem? The answer is that for a frictionless plane surface, not much. piawest.com
