Projectile Motion Reading

The last unit is really a throw-back to a previous unit....kinematics.  During this first week, we will be looking at x-velocities and y-velocities, so you will need to find those 4 kinematic equations and realize that a(gravity) here on earth is about 10 m/s/s.

We'll start with a concept review.   Go through the notes found at6

Physics Classroom

(there are 6 sections).

Show me your notes when you are finished.

After that, let's think about the easiest application of all for projectiles:   catapults!  These monsters are fun to make, but we are interested in physics, not just mayhem.  So, for the point of this class the catapult must be capable of flinging either:

• a marshmallow
• a mini candy bar
• a dry package of ramen noodles

and hitting a target that is 3-4 meters (that's 10-13 feet) away.  You will be judged on the ACCURACY of your catapult.

We will build these tomorrow after the quiz, so you MUST bring materials to work on.
