Gizmos Student Exploration: Golf Range Answer Key 100% Complete Solutions.

A shot with a very high angle because it will travel far due to the parabolic shape it will create and

fall down once the gravity has fully taken the ball down with it.

This might be because a golf ball is completely still before it’s even hit and a baseball would be

spinning through the ball before it was even hit, creating opposite forces.

Not far enough.

What were the velocity and launch angle values?

Yes, 70 m/s and 27 degrees.

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.

2. Golf drives travel much farther than Major League home runs. Why might this be?

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?

2. Click Reset ( ). Move the vinitial and θ sliders to adjust the velocity and launch angle until you get ahole-inone. (With the Gizmo sound on ( ) you will hear “Hole in one!”)

3. Can you get holes-in-one using other combinations of vinitial and θ? If so, give an example.

What launch angle do you think will yield the longest drive?

Look closely at the trajectory. Does it appear symmetrical?

The trajectory would not be very far because the ball would halt in the middle of space and

float due to the extremely thin atmosphere.

Activity A:

Maximum

distance

Get the Gizmo ready:

● Click Reset and check that Atmosphere: Air is selected.

● Set vinitial to 75 m/s and θ to 45.0 degrees.

Question: What launch angle will produce the longest drive?

1. Form hypothesis:

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? 43 degrees

B. How far did the ball travel? 375 meters

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.

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? 41 degrees

B. How far did the ball travel? 570 meters

C. Why do you think the ball traveled farther in this

situation?

There is no air resistance that limits therange of

the ball.

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?

No

45 degrees
