In the
video below, we can see an example of projectile motion; the motion of the
tennis ball when it leaves the hands of Joie (left) and the distance it
traveled it hit the ground. The shape of the ball as it falls toward the ground
is called parabolic motion. Now although you cant really see how high Joie is
off the ground, she is standing on a tall chair that makes her about 6 feet off
the ground and she threw the ball with an initial speed of 0.2 meters per
second. How would we use math to determine where on the ground the ball landed?
Well, by using physics we can
determine where the ball landed without actually measuring how far away from
Joie it landed. But before we know far away it landed we have to figure out how
long it was in the air. By using the d=1/2at^2 formula we can determine the
time, then we would go on to use the d=vt formula to find the distance and it
is as simple as that!
