so talking about projectile motion today, after watching a few random videos of projectile motion in action in real life.. ie people jumping, flying around etc. a lot of ski bail videos too haha.
when talking about projectile motion, horizontal velocity is constant, but vertical is not. this can be shown with a diagram that follows an object being for example thrown, and ruled from the centre.
usually we get a parabola-like shape for these kinds of diagrams, and they are symmetrical about a vertical line somewhere in the middle, this is assuming air resistance doesn't really affect the throw (like it would with say a ping pong ball) also the time it takes on either side of that vertical should be equal.
i cant remember much else we talked about.. but mr pitt said he would send us an email witht he powerpoint that we used today.
