Gizmos Student Exploration: Golf Range

Gizmos Student Exploration: Golf Range Name: Steve Peralta Date: 10-2-20 Student Exploration: Golf Range Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: acceleration, air resistance, gravity, hang time, launch angle, projectile motion, trajectory, vector, velocity Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. You are in a contest with your friends to see who can drive a golf ball the farthest. Should you hit a “line drive” (low to the ground) or a shot with a very high angle? Explain. At very high angle because that means the ball will go a lot farther with the angle you hit it 2. Golf drives travel much farther than Major League home runs. Why might this be? The ball is heavier than major league home runs because the ball has a smaller surface ear and there is not much wind resistance Gizmo Warm-up Have you ever hit a hole-in-one? You will have a chance to do that in the Golf Range Gizmo, where you will see how a variety of factors affect the path of a golf ball. The movement of objects such as a ball through space is called projectile motion. 1. Press Play ( ). Did the ball go too far, the right distance, or not far enough? The ball did not go far enough 2. Click Reset ( ). Move the vinitial and θ sliders to adjust the velocity and launch angle until you get a hole-in-one. (With the Gizmo sound on ( ) you will hear “Hole in one!”) What were the velocity and launch angle values? 65 m/s and 45 degrees 3. Can you get holes-in-one using other combinations of vinitial and θ? If so, give an exampl
