1. Golf Range Gizmo Section 5

2. What Do You Think Now? • Angle? • Height? • Speed?

3. For a ball thrown straight up: Accel on way up: -10 m/s/s Speed at top: 0 m/s Accel on way dn: +10 m/s/s

4. F. None of Choices • Which diagram (if any) might represent ... • 1. The initial horizontal velocity? • 2. The initial vertical velocity? • 3. The horizontal acceleration? • 4. The vertical acceleration? • 5. The net force?

5. Varying Angles 60° 45° 90° 30° 15°

6. Varying Height 40 m 30 m 20 m 10 m 0 m

7. Varying Speed 70 m/s 65 m/s 75 m/s 60 m/s 80 m/s

8. Vocabulary • Trajectory – a path, progression, or line of development • Parabola – a plane curve; the shape of a projectile

9. Practice • Bella jumps off the cliff, which is100 m, at 3 m/s west • a) In which direction is Bella accelerating? • b) How many seconds does it take Bella to hit the water? • c) How far is Bella from the cliff when she hits the water?
