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 s liders 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 example.
100 m/s and 72 Degrees. 64 m/s and 43 degrees.

, Activity A: Get the Gizmo ready:
Maximum ● Click Reset and check that Atmosphere: Air is selected.
distance ●
Set vinitial to 75 m/s and θ to 45.0 degrees.
Question: What launch angle will produce the longest drive?
1. Form hypothesis:
What launch angle do you think will yield the longest drive? 45 Degrees
2. Experiment: Turn on the Show grid checkbox. With the velocity set to 75 m/s, experiment with a variety of
launch angles until you find the one that yields the longest driving distance.
A. What launch angle produced the longest drive? 41 degrees
B. How far did the ball travel? 355m
3. Observe: Click Reset and turn on Show paths. Click Clear paths. Take a swing with the optimum launch
angle. The curved path the ball takes through the air is its trajectory.
Look closely at the trajectory. Does it appear symmetrical? No
The curve is slightly steeper on the right than on the left as a result of air resistance.
4. Experiment: Click Reset, then select Atmosphere: None. As before, use trial and error until you find the
launch angle that produces the longest drive.
A. What launch angle produced the longest drive? 44 degrees
B. How far did the ball travel? 555 m
C. Why do you think the ball traveled farther in this It traveled that far because there was no
situation? air resistance
5. Extend your thinking: The Moon has much less gravity than Earth and has an extremely thin atmosphere.
How would these factors affect the trajectory of a golf ball on the Moon?
The ball on the moon would be a lot greater than the golf ball on earth because on the
moon is a vacuum there is no air resistance to slow it down
