This
simulation is about objects that describe curves in a 2D plane under
the influence of gravity. A footballplayer that shoots a ball from
the ground, a basketballplayer that aims at a hoop and a canon that
shoots from a certain height are part of this package. In each
animation the speed in both x and ydirection are depicted at every
point in time by means of speed vectors. The formulas used are
typically:
It
becomes clear that vx doesn’t change with time because no friction
is implemented. Also, it can be seen from both animation and diagram
that speed is the derivative of place to time. Resultant speed is
mentioned as well. Assignments are about covered distance and for
instance about the value and direction of v_{y} or v_{x}
at a certain point in the curve.
Feedback
is included for context 1 and 3. The “basketballer" context
contains no questions yet and has a few flaws here and there.
