AP PHYSICS 1 FORMULA SHEET HOW TO

Has all of these things and doesn't have delta x, since we don't know delta x and we're not looking for it either. Look at these equations and identify one that So we had analyzed this question and we see that, actually, the change in distance didn't appear anywhere in this question, it's just these four values right here. So let's fill that in, that's zero meters per second. And then if we keep going, it says, 'Starting from rest.' So that's saying that at theīeginning when it starts, it's at rest, which means it has zero for it's initial velocity, it's just sitting there. So anyway, 80 kilometers per hour, per hour. Yourself what is this symbol really talking about. Whatever notation you use, that's fine, but make sure to ask Right here written as V sub f to really explicitly say So that's the final velocity or just our velocity at the time here. When it's done speeding up, it'll be going at 80 kilometers per hour. To reach its top speed of 80 kilometers per hour? That's saying its top speed All right, so if we keep going here, we get, all right, how long does it take We don't know what it is yet,īut this is our question, we're being asked about the time. There's some more stuff afterward, but that by itself is justĪsking about the time, how long does it take? All right, so let's note thatīy circling this time here. The beginning and say, 'How long does it take?' That by itself is a question. Hour starting from rest? So that one's a littleīit more complicated, there's more going on in here. To reach its top speed of 80 kilometers per

The acceleration is 1.35 meters per second squared. So that's pretty direct, it's just telling us A light rail commuter train accelerates at a rate of 1.35 meters Hour starting from rest?' All right, so let's unpack To reach its top speed 'of 80 kilometers per So the question says, 'A light rail commuter train 'accelerates at a rate of 1.35 With that out of the way, let'sĭive into our example here. Use when we understand where they come from.

And that's what these equations are like, they're tools that we can But once you understand that, the calculator is a really valuable tool. To multiply and divide, so you know what a calculator

It's important to know how to add, subtract, Like using a calculator where they help you save time. But once you have that understanding, these equations are kind of Videos that go through that and can help you build that understanding. Strong understanding of position and velocityĪnd acceleration and time and how they're all So before we jump into the examples, I wanna say that it is very important to understand where these equations come from to really develop a Of these equations over here will be the most usefulįor helping us solve it. We're not going to solve them, we're just going to look at what we know and what the question is asking for and then identify which one We're going to go through a few examples of setting up some problems with constant acceleration.
