[0:03] We're learning about how we can [0:04] calculate the forces involved with an [0:07] angled projectile. [0:08] >> Projectile motion is kind of a key part [0:10] of physics. And if we want to be able to [0:12] really make predictions about where [0:13] things are going to go, we have to be [0:14] able to launch things at a consistent [0:16] speed. This gives us the opportunity to [0:18] actually do that. [0:19] >> We were shooting a ball out of the [0:20] launcher and trying to put certain rings [0:22] that the ball should go through. and [0:24] everyone in the class had to put it at a [0:26] different point and calculate how high [0:28] the ball was going to be at that point. [0:29] >> We're looking at their velocities and [0:31] like displacements. It's awesome for me [0:34] to really apply what we're learning in [0:36] real life. [0:36] >> It's still like a real life example of [0:38] how what we're learning is applied to [0:40] the real world. [0:40] >> Thank you very much for providing these [0:42] for us. They will be used in really all [0:45] of the different physics classes.
