1. Okay, so you have this amazing new skill, and you can calculate all sorts of motion problems.
2. Now, can you calculate every motion problem?
3. The answer is not quite yet.
4. There are two types of problems we still can't solve.
5. We can't solve problems where an object starts with some initial velocity,
6. and we can't solve problems where the object moves in two dimensions,
7. but we'll get to that later.
9. The variable we're going to use to talk about initial velocity is V with the subscript 0.
10. This comes from the idea that when we start a problem
11. we usually start our timer at 0.
12. So this is at time equals 0 what is the velocity?
13. Let's think back to Galileo standing on top of the leaning tower of Pisa.
14. This time around, instead of just having him drop the ball,
15. let's imagine he could throw the ball straight down with different initial velocities.
