Team Name – Catapult Class Period - PHYSICS Your name Date Abstract: Answer the following questions in paragraph form. Para 1: Why did we do this lab? Para 2: How did you and your team come up with the design of your catapult? Para 3: What did you like about this lab and why? Objectives: List 5-10 purposes for this lab (i.e. 1. To calculate force) Equipment: List materials used Safety Rules: List at least 5 rules of safety for this project Procedure: 1. Give step by step how to build the catapult 2. Explain how to work the catapult Data: Create a data table with the following information Data needed Horizontal distance Time travelled Angle of catapult Test trial at home Trial 1 Trial 2 Trial 3 Average for trials Calculations: give equations and solve What to calculate Height of trajectory = ∆𝑥 ( 4 ) 𝑡𝑎𝑛𝜃 Launching initial 𝑔∆𝑥 𝑠𝑖𝑛2𝜃 velocity = √ Equation Height = (horizontal distance travelled divided by 4) times tangent of the catapult angle Square root of ( (gravity times the horizontal distance travelled) divided by (sin of 2(angle of the catapult))) Plug in Solve with answer Results: 1. list who is in your group and what each person did, 2. list 3 things you and your group learned by doing this project, 3. Attach 2- 6 pictures of your group throughout this project (building, working, and group photo with completion of catapult) Conclusions: 1. 2. 3. 4. compare and contrast speed and acceleration, Compare and contrast force and acceleration. Explain how to use the kinematic equations. Draw the projectile motion created by your catapult. Label. Calculate the height achieved by your catapult. 5. Draw the catapult ball and label all the forces involved (do a free body diagram) 6. Discuss all 3 Newton’s Laws and how they specifically applied to your project. Discussions: answer the following questions 1. 2. 3. 4. 5. 6. List at least 5 observations made during the experiment List 3 potential sources of error and how could you have reduced that error. How was force utilized in this project? How was acceleration important to this project? Did you like this project? Why or why not? Describe the historical development of force and motion and how it was used in your catapult. 7. How does physics help YOU in your life now? 8. How will physics help YOU in your life in the future?
