oakesj@corydon.shcsc.k12.in.us Subject: Physics Topic: Projectile Motion Grade Level: High School IN Standards: P.1.5, P.1.6 ISTE Student Standards: 1, 5, and 6

Students will use the websearch to learn about free fall and projectile motion.

1. What is free fall?

2. What does free fall acceleration cause the falling object to do?

3. What happens if an object is fired up with an initial velocity?

4. Describe what happens to an object when it is fired horizontally.

5. Describe what happens to an object when it is fired at an angle.

6. How is this different from free falling object?

7. In what two directions is an object moving when it is fired at an angle?

8. Why is the motion of an object fired at an angle also known as parabolic motion?

9. What is acting on an object in parabolic motion after it has been fired?

10. Describe the differences in the path of two objects if one object is fired at 10 m/s at an angle of 20 degrees, and the other object is fired at 10 m/s at an angle of 70 degrees.

11. Find the angle that will fire an object the farthest if the projectile is fired at 8.5 m/s.

Follow-up Activity

After lecture tomorrow use the equations you learned to prove that the angle you found in number 11 is correct.
