Understanding the Gravity Pitch Gizmo
What is the Gravity Pitch Gizmo?
The Gravity Pitch Gizmo is an interactive simulation designed to demonstrate how gravity influences the trajectory of projectiles. It allows students to manipulate variables such as launch angle, initial velocity, and height to observe how these factors affect the path of an object under gravity. The Gizmo provides real-time graphs, animation, and data tables to facilitate exploration and experimentation.
The core learning objectives of the Gravity Pitch Gizmo include:
- Understanding the components of projectile motion
- Analyzing how initial velocity and launch angle influence range and height
- Applying physics equations to predict projectile behavior
- Interpreting data from simulation outputs
How Does the Gizmo Work?
The simulation typically involves:
- Setting initial parameters: launch angle, initial speed, and starting height
- Launching the projectile and observing its trajectory
- Viewing graphs of velocity, acceleration, and displacement over time
- Recording data points such as maximum height, time of flight, and range
This hands-on approach allows learners to test hypotheses and visualize the effects of different variables, making complex physics concepts more accessible.

Sample Problems and Solutions from the Answer Key
Problem 1: Calculating Range of a Projectile
Question:
A projectile is launched from the ground at an initial speed of 20 m/s at an angle of 45°. What is its approximate range?
Solution Overview:
- Use the projectile range formula:
\( R = \frac{v^2 \sin 2\theta}{g} \)
- Plug in values:
\( v = 20\, \text{m/s} \), \( \theta = 45^\circ \), \( g = 9.8\, \text{m/s}^2 \)
Calculation:
- \( \sin 2\theta = \sin 90^\circ = 1 \)
- \( R = \frac{(20)^2 \times 1}{9.8} = \frac{400}{9.8} \approx 40.82\, \text{meters} \)
Answer:
The projectile’s approximate range is 40.8 meters.

Problem 2: Effect of Launch Angle on Maximum Height
Question:
How does increasing the launch angle from 30° to 60° affect the maximum height of a projectile launched with the same initial speed?
Solution Overview:
- The maximum height \( H \) is given by:
\( H = \frac{v^2 \sin^2 \theta}{2g} \)
- Calculate for each angle:
Calculations:
- For 30°:
\( H_{30} = \frac{(v)^2 \sin^2 30^\circ}{2g} \)
\( \sin 30^\circ = 0.5 \)
\( H_{30} = \frac{v^2 \times 0.25}{2 \times 9.8} \)
- For 60°:
\( \sin 60^\circ \approx 0.866 \)
\( H_{60} = \frac{v^2 \times 0.75}{2 \times 9.8} \)
Conclusion:
Since \( \sin^2 60^\circ \) is greater than \( \sin^2 30^\circ \), increasing the launch angle from 30° to 60° results in a higher maximum height.
