Play the animation (the first case is shown). You will see the
magnitude of the velocity indicated for each of the three projectiles.
Assume you are looking at an X vs Y graph with the distances measured
in meters and the time in seconds. As you answer the questions below,
try the other cases also.
Questions :
A) For each of the projectiles, when is the magnitude of the
velocity a minimum (i.e., conceptually where is the projectile in its
flight)? When is it a maximum?
B) How do the Vx velocities change for each of the objects (Use
the Vx button) - is this to be expected? Why?
C) How do the Vy velocities change for each of the objects (Use
the Vy button) - is this to be expected? Why?
D) How does the variation in the Vx components of the three
objects relate to the horizontal distances the objects go?
E) How does the variation in the Vy components of the three
objects relate to the vertical distances the objects go?
