2. After "playing" with the applet, develop a hypothesis. For example, "We think that there is a correlation between the mass of the projectile and how far it goes."

 * Applet:**


 * HYPOTHESIS???? Write it below.**

We are going to test different projectiles being shot while all other parameters remain constant. The heavier projectiles should travel lesser distance than lighter ones.

3. Develop an experimental procedure. Write it below.
we will shoot all projectiles using the following parameters - angle of cannon elevation - 45% - initial speed 10m/s -air resistance will not be accounted for.

4. Data. Enter it below.

 * Projectile || Distance traveled (m) ||
 * tankshell || 11.3 ||
 * goldball || 11.3 ||
 * piano || 11.3 ||
 * buick || 11.3 ||

5. Conclusions. Write them below. Was your hypothesis correct or not?
It has been discovered that the applet doesn't account for the mass change and needs to be fixed. include component="comments" page="space.template.Parabolic" limit="10"
