This activity (page 2 of the PDF) is a full inquiry investigation into how ordinary things behave in microgravity, similar to what astronauts experience. Groups of learners will prepare a large drop box, complete with wireless camera, to drop off a balcony with an everyday phenomenon (e.g. burning candle, fizzing seltzer tablet, swinging pendulum) inside. After observing the object in ordinary gravity, it is placed inside the drop box and dropped so the camera can record images during free fall for analysis. Relates to linked video, DragonflyTV: Microgravity. (less)

The Ejs Free Fall Cartesian model displays the dynamics of a ball dropped near the surface of Earth onto a platform. The initial conditions for the ball are an initial positive velocity in the x direction and zero initial velocity in the y direction. The coefficient of restitution for the ball’s collision with the platform is less than one. You can modify this simulation if you have Ejs installed by right-clicking within the plot and selecting “Open Ejs Model” from the pop-up menu item. Ejs Free Fall Cartesian model was created using the Easy Java Simulations (Ejs) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_newton_FreeFallCartesian.jar file will run the program if Java is installed. Ejs is a part of the Open Source Physics Project and is designed to make it easier to access, modify, and generate computer models. Additional Ejs models for Newtonian mechanics are available. They can be found by searching ComPADRE for Open Source Physics, OSP, or Ejs. (less)

The Falling Slinky model approximates a slinky using twenty masses connected with light springs. The slinky is suspended from one end and released.

The Ejs Free Fall 3D model displays the three-dimensional dynamics of a ball dropped near the surface of Earth onto a platform.

Free Fall Air Resistance Model

This simulation allows students to compare the motion of free falling objects with and without the influence of air resistance. Air resistance is the result of collisions of the object's leading surface with air molecules. On Earth, objects falling through the air usually encounter some sort of air resistance, though the amount is dependent upon several factors. In this model, a blue ball falls under the influence of gravity alone. A falling red ball is subject to both gravity and air resistance. Students can adjust the amount of air resistance with a slider. When the simulation is played, graphs are simultaneously plotted that show position vs. time, velocity vs. time, and acceleration vs. time for <u>both</u> falling balls. <b><i>See Annotations</b> for an editor-recommended, interactive tutorial that further explains free fall and air resistance.</i> This item was created with Easy Java Simulations (EJS), a modeling tool that allows users without formal programming experience to generate computer models and simulations. To run the simulation, simply click the Java Archive file below. To modify or customize the model, <b><i>See Related Materials</b> for detailed instructions on installing and running the EJS Modeling and Authoring Tool. </i> (less)

In this physics activity, learners conduct two experiments to explore free-falling. In the first experiment, water-filled plastic bottles with holes in them spurt water under normal conditions, but don't leak while in free-fall. In the second experiment, a ping-pong ball in a water-filled plastic tube floats upward under normal conditions, but remains motionless when the tube is dropped or thrown. Educators can use pre-assembled materials for group demonstration purposes. Note: this activity will get the floor wet, so consider doing this outside. (less)

This simulation allows students to examine the motion of an object in free fall. <i><u>Download below.</i></u> The user can control the initial height (0-20m), set an initial velocity from -20 to 20 m/s, and change the rate of gravitational acceleration from zero to 20 m/s/s (Earth's gravitational constant is ~9.8 m/s/s). Students can also launch the ball upward from any point on the line of motion. The free fall is displayed as a motion diagram, while graphs are simultaneously displayed showing position vs. time, velocity vs. time, and acceleration vs. time. <b><i>See Annotations</b> for an editor-recommended tutorial that further explains how graphs are used to represent free fall motion.</i> This item was created with Easy Java Simulations (EJS), a modeling tool that allows users without formal programming experience to generate computer models and simulations.

This is an interactive homework problem for introductory physics students relating to motion in two dimensions. Two boys, at a distance 63 meters apart, are playing catch. Given the initial speed and angle of projection of the thrown ball, how far must the catcher move to catch it? A user-activated "help" sequence is provided for each step of the problem-solving, from conceptual analysis through quantitative calculation. To promote critical thinking, immediate feedback is received for both correct and incorrect responses. This item is part of a larger collection of interactive homework problems for introductory physics. (less)
