## Rolling Resistance Physics Lab

*Rolling Resistance*

Rolling resistance is a force that opposes the motion when an object rolls along a surface.There are many examples of objects experiencing rolling resistance: car or bicycle tires on pavement, skateboard wheels on a half pipe ramp, steel wheels on a railroad track, ball bearings in a pulley, bowling balls on a bowling lane, and carts rolling on a dynamics track, just to mention a few. Many factors can affect the magnitude of the forces associated with rolling resistance.

## Moment of Inertia Challenge

*The Moment of Inertia Challenge*

Determinig the moment of inertia about the center of mass *mathematically* of an object with complex geometry is not an easy task. Consider, for example, the empty 3D filament reel shown in Figure 1, an empty 1-kg Polymaker Polylite™ PLA reel. With its holes and intricate axle design, the best way to determine the moment-of-inertia about its center of mass is via a laboratory experiment. Voyager (or PocketLab One) is mounted to the reel for data collection.

## Kinematics of Translational and Rotational Motion

*Introduction*

Empty 3D filament reels are great devices to use in the physics classroom. There's a good chance that you and your students could come up with some interesting physics lab investigations using these reels. Attach Voyager or PocketLab One to the reel as shown in Figure 1, and the possibilities are endless! This lesson describes a lab in which your students study the kinematics of both translational and rotational motion when the reel rolls down a ramp on its axle. Students are often surprised when they see the reel speed up upon reaching the floor on which

## Moment of Inertia of a 3D Filament Reel About Its CM

*Introduction*

Your school can put all of those empty 3D filament reels to good use in the physics classroom. There's a good chance that you and your students could come up with some interesting physics lab investigations using these reels. As shown in Figure 1, attach Voyager or PocketLab One to the reel, and the possibilities are endless! This lesson describes a lab in which your students determine the moment of inertia of an empty 3D filament reel about its center-of-mass. They will accomplish this using two independent methods. One method has the reel acting as a p

## Unrolling Spool Problem Quantitative Experiment

*Introduction*

Think twice before discarding your school's empty 3D filament reels. There's a good chance that you and your students could come up with some interesting physics lab investigations using these reels. As shown in Figure 1, attach Voyager or PocketLab One to the reel, and the possibilities are endless! This lesson describes a quantititive experiment that your students can perform in a study of the classic "unrolling spool problem".

## Periodic Motion of an Empty 3D Filament Reel

*Introduction*

Don't discard your school's empty 3D filament reels. There's a good chance that you and your students could come up with some interesting physics lab investigations using these reels. Attach Voyager or PocketLab One to the reel and the possibilities are endless! This lesson describes a unique experiment in which * periodic motion* is investigated using an empty 3D filament reel. Depending on the teacher's goals and amount of detail in the analysis of collected data, this lab could be used from the 4th grade through high school. The

## NGSS Seismic Basketball Challenge

*The NGSS Seismic Basketball Challenge*

This NGSS seismic basketball challenge fits well in the study of motion for high school physics students. Here is a statement describing the challenge:

Place PocketLab Voyager on a wood floor with accelerometer data being captured. Drop a basketball onto the floor near Voyager and let it bounce several times, being careful to not let it hit Voyager. From the recorded accelerometer data, determine the

## Intelino / Voyager Lab: "Floor-it" Acceleration/Max Speed

*Introduction*

The purpose of this lesson is to challenge your students to design an experiment for which data from PocketLab Voyager is used to determine the "floor-it" acceleration and maximum speed of the intelino smart train engine. Required data should be obtained in a single run of data collection by the PocketLab app. Figure 1 shows a picture of Voyager attached to the top of an intelino smart engine. Designed for all ages, intelino is intuitive with its app, has built-in sensors to provide an interactive experience for the user, and is easily programmed with colo

## intelino / Voyager Lab: Stopping Distance vs. Speed

*Introduction*

Have you ever been told not to follow too close to the driver ahead of you? To keep a safe distance? To abide by the "3-second rule"? To keep a distance of at least one car length for every ten miles per hour of speed? These questions all deal with the issue of stopping distance versus speed in order to avoid crashes. A great way to investigate the relationship between stopping distance and speed is to interface Voyager with an "intelino® smart train". Designed for all ages, intelino is intuitive with its app, has bui

## intelino / PocketLab: Velocity vs. Impulse to Stop

*Introduction*

While driving at 40 mph, you see a red stop light ahead. You press your brakes for several seconds, gradually coming to a stop. A little later on the same road at 40 mph, you approach another light, this time green. While approaching this light, it suddenly changes to yellow. You make a split-second decision to put on your brakes to avoid going through a red light. With the brakes applied quite hard, you quickly stop, waking up your sleeping friend in the front passenger seat.
