Throttle response:Eco mode may reduce how reactive your gas pedal is to pressure, which might desensitize your car’s throttle to sudden inputs. As a driver, you may feel that your car generally performs a littl
What is the acceleration of a car, in terms of g, which is going at a speed of 43 mph in a circle of radius 48 feet?Circular Motion:Centripetal Acceleration is when the acceleration of a body is directed toward the center of a circular pa...
Roadshow: What to do if your car suddenly acceleratesGary Richards
What is the average velocity of a car that accelerates from 10mi/hr to 45mi/hr ? What is the acceleration of a vehicle that changes its velocity from 400 km/h to a dead stop in 10 s? A car, initially moving at 60 \text{ mph} , ...
Locking the transmission to lower gears will force the engine to spin faster and generate higher RPMs. Frequent driving in “L” mode decreases fuel economy and accelerates engine and transmission wear. If the current conditions no longer require “L” mode, always set the transmission to “D”...
These are two different questions, and might have two different answers. When a car accelerates, a goodly amount of momentum is necessarily transferred across the car/road boundary. In contrast, in the center-of-mass frame, virtually no energy is transferred across the car/road boundary. In an...
The big engine is heavier than the small engine, so the car uses extra energy every time it accelerates or drives up a hill. The pistons and other internal components are heavier, requiring more energy each time they go up and down in the cylinder. The displacement of the cylinders is lar...
Brakes and acceleration:These are both critical to your driving experience and safety. As you drive, take note of how the carbrakesand accelerates. Is it appropriately responsive for your style of driving or will it require significant re-adjustment on your part?
Question: What is the speed of a car if it travels 200 meters in 30 seconds? Speed Speed measures the how fast an object is moving, which is determined by how much distance it travels over an amount of time. Its SI units are m/s (meters per second), however if you use othe...
A‘catalyst’ is a substance that accelerates a chemical reaction, and within a catalytic converter, there are two types of catalyst. The first is a reduction catalyst which uses platinum and rhodium within the honeycomb to reduce NOx emissions. NOx is produced by nitrogen oxide and nitrogen dio...
