speed
In everyday use and in kinematics, the speed (commonly referred to as v) of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity. The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. Speed is the magnitude of velocity (a vector), which indicates additionally the direction of motion.
Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second (m/s), but the most common unit of speed in everyday usage is the kilometre per hour (km/h) or, in the US and the UK, miles per hour (mph). For air and marine travel, the knot is commonly used.
The fastest possible speed at which energy or information can travel, according to special relativity, is the speed of light in vacuum c = 299792458 metres per second (approximately 1079000000 km/h or 671000000 mph). Matter cannot quite reach the speed of light, as this would require an infinite amount of energy. In relativity physics, the concept of rapidity replaces the classical idea of speed.
Using a 22kW type 2 PodPoint but it’s only charging at 5.9kW.
Battery was 56% charged so assume the lower rate is due to the battery level vs charging profile?
Not sure if i doing something wrong here but any advise would be appreciated - SE SR received yesterday - first time charging today at work on the 22kw charger using the MG supplied 32a type 2 cable but i'm only getting 3.27kw charging power, i would have expected around 7kw - battery was at 69%...
Hi everyone
Collected my blue SE last week - overal very happy with the car , but just noticed when I going to highway and try to spped up from approx 60 kmph , the pedal, even I push the pedal to the floor, car accelerate very slow , takes a while to reach 100 kmph ..
I noticed similar...
Just bought a new MG ZS EV 2023 Long Range Trophy. I noticed that it can not read some speed limit road signs. I realized that in can only read signs that are available in UK in miles/h and not those available in other Europe countries where km/h is used.
For example it will not read road signs...
My MG5 arrived at a speed charger with 9% of charge left. After plugging it in, the charger balked - and subsequently, starting was impossible as well as charging. The Tesla supercharger at 5 m distance gave the same negative result. My MG5 is now towed away in a country with few MG dealers 1000...
Driving Normal mode on the motorways, I find trying to increase my speed from 65 to say 70 or 75 is very slow. In fact sometimes I feel it is not going to make it and then I see oh it has, so it must be slowly.
At low speeds the acceleration is very very good. Exciting even.
I was under the...
