More on graphical solutions to projectile motion problems
In my previous post on solving projectile motion problems graphically, I mentioned that it should be possible to overlay the trajectory of the projectile onto this construction and animate it in geogebra. After some fiddling with geogebra, I was able to produce this video.
In the animation, increases with time, and the average velocity is computed as the sum of and . When this vector is scaled by the time (), you get a displacement vector from the origin to the current location of the projectile.
If you want to play with the improved geogebra file, here’s a link.
