(or the Unit 2 Voicethread, but who wants that as the title?)
Why hello, it seems you've stumbled upon something suspicious, me, holding a gun. WAIT! WHAT!? But why?
For the sake of Physics of course!
In this unit, we've been learning about what objects do when affected by different types of motion: Free Fall, Free Fall with Air Resistance, and even Newton's second law. But the thing I've found most difficult to understand (and hope to understand better by explaining it to you) is what an object does when thrown at an angle.
We've had two examples in class of what happens when things are fired out of guns: The example we did in Ms. Cianciulli's class of shooting you, our dear Mrs. Lawrence in the face (it was pretty gruesome when you think about it). And the man attempting to tranquilize the monkey and what happens if the monkey lets go of the branch he is sitting on (provided the man is firing straight at the monkey).
But I wanted something I was familiar with, and so here I am shooting a weapon of in the distance on an Idaho farm. Though I was aiming my sight dead ahead to the center of the target, I missed the coveted bull's eye every time and now, because of this class, I understand why! Objects travel in a parabolic trajectory, like an arc, meaning they fall lower than they start. Therefore, when the bullet is fired out of the gun it lands below the sight, so in order to get an accurate shot, I would have to aim a bit higher so that when the bullet falls it hits dead enter.
Hey Becca this was a really good post. Who would have guessed that you shoot guns? But it was actually helpful having proof that the bullet does sink because of gravity instead of just trusting physics that it would happen. And bravo on the entertaining blog post once again!
