Witryna17 paź 2024 · Therefore, reducing the size of the separation zone, which is the area behind the car containing the vortices behind the car, is one of the predominant methods of decreasing aerodynamic drag. This can be done by slightly tapering the rear end … Witryna25 lut 2024 · How can we decrease friction in walking. A ball bearing is placed between two surfaces that must spin over one another. The axle is attached to the inner side of a ball bearing, while the wheel is attached to the outer side of the ball bearing. By causing the two surfaces (wheel and rear axle) to roll over each other, they reduce friction.

WitrynaKeeping the body aligned requires having a tight core. Keep the head down. Keeping the head down helps keep it in alignment with the body, but more importantly, a head down also can help reduce surface or wave drag. There is actually less drag underwater than on the surface of the water (think of a submarine), because we eliminate surface drag. Witryna27 lip 2024 · 6. You have low compression. If your engine has gone completely bad, and you have lost compression, this can cause a massive decrease in gas mileage. Compression is what allows your engine to create the power it needs to run. When it’s low, your car will use more gas and run less efficiently. 7.
