Physics/Notes 6.1
- 1. Motion in Two Dimensions
- 2. Section 6.1 Projectile Motion How do I separate projectile motion into horizontal and vertical components? How can I utilize kinematic equations to solve projectile motion problems?
- 4. Path Path? Trajectory – the path of a object experiencing projectile motion
- 5. Projectile Motion Projectile – an object shot through the air Can be anything Kinematic Equations apply While the projectile is traveling we can draw a free body diagram
- 6. Free – Body Diagram
- 7. From a cliff… If I drop a ball off a cliff, what is the force acting on it? What if I push it off the cliff? What if I shoot it up at an angle off the cliff?
- 8. Gravity! Gravity is the only acceleration in projectile motion problems Does gravity apply horizontally? Is there any acceleration in the horizontal direction? Application to equations?
- 9. Trajectories of Two Softballs Total Time?
- 11. Strategies List Data by Horizontal and Vertical What is the initial horizontal velocity? What is the initial vertical velocity? Is there a launch angle? What is the launch height? What is the launch length?
- 12. Velocity Components What if Vx = 8 m/s and Vy = 10 m/s?
- 13. Examples A bowling ball is rolled off a 50 m high cliff with a velocity of 5 m/s. How long does it take the ball to reach the ground? How far from the base of the cliff does the ball hit the ground? What are the horizontal and vertical components of the velocity just before it hits the ground?

- 16. Short Cuts
- 17. Example A ball is launched at 4.5 m/s at 66° above the horizontal. What are the maximum height and flight time of the ball?
