Drag power equation
WebMay 18, 2024 · Net Force = Engine Force - Drag Force = Power / Velocity - Velocity² I'd like to determine power based on how fast I want a car of a given mass to reach a given speed, for example, 0 to 20 m/s in 10 seconds for a 1000 kg car. Here is the equation I came up with to calculate the power needed without any drag: Using it to solve the example: WebUsing the equation for drag force, we have mg= 1 2ρCAv2 m g = 1 2 ρ C A v 2 . Solving for the velocity, we obtain v =√ 2mg ρCA v = 2 m g ρ C A. Assume the density of air is ρ = …

WebMar 26, 2016 · In physics, you can calculate power based on force and speed. Because work equals force times distance, you can write the equation for power the following way, assuming that the force acts along the direction of travel: where s is the distance traveled. However, the object’s speed, v, is just s divided by t, so the equation breaks down to.
