What Is the Free Fall Laboratory Gizmo?
The Free Fall Laboratory Gizmo is an interactive online simulation designed by ExploreLearning that allows students to explore the physics of objects falling under the influence of gravity. It offers a virtual environment where learners can manipulate variables such as mass, height, and air resistance to observe their effects on falling objects.
This Gizmo is particularly popular in middle and high school science classes because it visually demonstrates the principles of acceleration due to gravity, terminal velocity, and the effects of air resistance. The Answer Key accompanying this Gizmo helps students verify their understanding and complete assignments accurately.

Key Concepts Covered in the Free Fall Laboratory Gizmo
Before diving into the answer key specifics, it's essential to understand the core physics concepts that the Gizmo explores:
1. Acceleration Due to Gravity
- Objects in free fall accelerate downward at approximately 9.8 m/s² on Earth.
- The Gizmo allows students to observe how objects accelerate over time when dropped from different heights.
2. Velocity and Time
- The relationship between velocity, acceleration, and time is key.
- Students can measure the velocity of a falling object at various points.
3. Air Resistance and Terminal Velocity
- Air resistance opposes the motion of falling objects.
- When the force of air resistance equals the gravitational force, objects reach terminal velocity and fall at constant speed.
4. Effect of Mass
- In a vacuum, all objects fall at the same rate regardless of mass.
- The Gizmo demonstrates how air resistance affects objects of different sizes and shapes.

Sample Questions and Answers from the Gizmo Answer Key
Below are typical questions from the Free Fall Gizmo, along with summarized answers and explanations to help you grasp the concepts.
Q1: What happens to an object’s velocity as it falls freely under gravity?
- Answer: The velocity increases linearly with time due to acceleration.
- Explanation: Since gravity causes constant acceleration, the object’s speed keeps increasing during free fall until it reaches terminal velocity or the fall ends.
Q2: How does air resistance affect the falling object’s motion?
- Answer: Air resistance opposes the motion, reducing acceleration and eventually leading to terminal velocity where acceleration stops.
- Explanation: As the object accelerates, air resistance increases until it balances the weight, causing the object to fall at a constant speed.
Q3: Does the mass of an object affect its rate of fall in a vacuum? Why or why not?
- Answer: No, in a vacuum, all objects fall at the same rate regardless of mass.
- Explanation: Without air resistance, the acceleration due to gravity is the same for all objects, making mass irrelevant to the rate of fall.
Q4: How can you determine the acceleration due to gravity in the Gizmo?
- Answer: By measuring the time it takes for an object to fall from a known height and calculating the acceleration using kinematic equations.
- Explanation: The Gizmo often provides tools or data to help perform these calculations accurately.
