When you throw an object into the air, its trajectory is a parabola. How do
its instantaneous velocity and the vertical and horizontal components of the
instantaneous velocity change over the course of its trajectory? What happens
when the initial speed is larger? Smaller? What happens if the gravity were
larger? Smaller? Zero? Negative? Holding gravity and the initial speed
constant, in which direction can you throw to make the object reach the
farthest point along the horizon?
