Right, so immediate acceleration is basically how fast something speed changes.
00:07
So the equation for that is acceleration is the change in velocity over a change in time.
00:17
And basically we just have to plug in the things that we know.
00:21
So this is the ending velocity or the velocity at time 2 minus starting velocity or the velocity at time 1 divided by how much time that takes.
00:37
So we said it was 50.
00:40
Is this miles or kilometers? kilometers.
00:45
50 kilometers per hour.
01:01
Minus 40 kilometers per hour.
01:12
And it happens in 10 seconds.
01:20
Okay.
01:22
So basically we have 50 minus 40 is 10 kilometers per hour per 10 seconds.
01:30
So if we subtract all that out, or sorry, if we subtract 40 from 50, and then divide by 10, we're left with one kilometer per hour per second.
01:56
And if we were to put this in more standard units, we could do some dimensional analysis to put this in either kilometers per hour squared or kilometers per second squared...
