**Introduction and Hypothesis**

The purpose of this experiment was to predict and verify the range of the object and the distance the object will fall. The information known about this experiment, is if you’re calculating vertical motion, you must take gravity into account. If you’re calculating the horizontal distance, there’s no gravity or acceleration being acted upon it and is at a constant velocity. All diagrams should include right triangles. Our hypothesis was, the smaller the angle, the farther the object will go.

**Materials and Procedure**

- 15 Popsicle sticks
- Tape
- Rubber bands
- 1 Plastic spoon
- Rubber screw
- 3 Rubber bands

- Measured the angle of how far back we held the spoon with a protractor
- Before it was launched we held the protractor directly next to the popsicle stick

**Results (Data table and graph)**

Yes, we hit our target on the 2nd try. It didn’t go in the basket but it did hit the front of it.

**Analysis**

Our hypothesis was correct, because the rubber screw was heavier, we didn’t have to worry about it launching too far away from of our targeted area even with the smaller angles we tested. We also thought it would hit the target. If given another chance to modify our catapult, we would make it simpler and give the spoon more leeway to move. From this experiment, we learned the difference between vertical and horizontal motion, and how a projectile works with an object.

This is a strong report. Your calculation is correct and easy to follow. I would recommend being more clear with how you set up the protractor when measuring the pull back angle of the catapult. A picture might help to clarify the position of the protractor. This looks like a professional web site and I noticed no grammar or spelling errors. Nice work.

Thank you! I will take that into consideration next time.
