| Jul 30, 2022 at 5:47 | comment | added | Fëakhelek | Also, I'm not taking physics classes now, I'm more of a dabbler. I don't really have the math background to go much further but I try to understand the concepts. For example, I recently learned to understand the 4 vector because in reading about relativity it seemed to me that we must be moving forward in the time dimension at the speed of light. I can't do the math but I grasp the idea, which is, to me, better than being able to do the math but not truly "grok" the concept behind it. | |
| Jul 30, 2022 at 5:40 | comment | added | Relativisticcucumber | no problem, glad it was helpful. so yes, vectors do have magnitude and direction. for acceleration, the magnitude is the amount that velocity is changing, and the direction is the direction of that change. for example if you are in a car that is decelerating, say at a rate of 10 km per second, your car is getting slower by 10km every second, so the magnitude of this acceleration is 10km, and the direction is backward (assuming you are driving forward on a road). Note your velocity is still forwards, but the acceleration describes how the velocity changes. @Fëakhelek | |
| Jul 30, 2022 at 5:32 | comment | added | Fëakhelek | First, Thanks for taking the time to write a great answer. So you say, "a is the acceleration vector". My (limited) understanding is that a vector requires a magnitude and direction, so to me "a" appears to be a scalar quantity. Can you clarify? | |
