Projectiles

  In this lab we learned about projectile motions, which are objects projected in the air at an angle. Projectiles constantly accelerating in the force that gravity is acting on. Because we live in a 3-Dimensional world, we can analyze them separately. To help explain and better our understanding of this, we did a lab of an example of a projectile. In our groups we made projectiles by shooting a basketball. We recorded our shots into video physics and it helped us create projectile graphs:

We can analyze these graphs by the x-dimension and y-dimension:

X-Dimensions:
In this dimension we learned that the object will always be moving at constant speed in  (top graph)x-time and (bottom graph) v-t and over time it gains distance. It never speeds up or slows down.

Y-Dimension:
In this dimension we learned that the object is constantly accelerating. In top graph, the object is moving up but slowing down and when it reaches its highest point it stops moving then moving down but speeding up. In the bottom graph, the object is accelerating too, like the top graph. Its moving up but slowing down then stops moving at its highest point then continues moving down  but speeding up in the negative direction.
