Activity 3—A Speedy Slide

Parabolic

 

 

You have been familiar with playgrounds and slides since you were a small child. The force of gravity pulls you down a slide. The force of friction slows you down. In the first part of this experiment, you will use a CBR 2™ motion detector to determine your speed or velocity going down a playground slide. In the second part, you will experiment with different ways to increase your speed going down the slide.

Objectives

In this experiment, you will:

0use a CBR 2™ motion detector to determine your speed going down a slide

0experiment with ways to increase your speed going down the slide

0explain your results

Data collection, Part 1, Sliding Speed

ÊConnect the CBR 2™ motion detector to the calculator using an appropriate cable (see below) and firmly press in the cable ends.

0 If TI-83 Plus, TI-89, TI-92 Plus, TI-89 Titanium, Voyage™ 200, use an I/O unit-to- unit cable

0 If TI-84 Plus, use a Standard-B to Mini-A USB cable (unit-to-CBR 2™)

ËOn the calculator, press Œand select EasyData to launch the EasyData App or press 2°and select RANGER if you are using a calculator that does not operate with EasyData.

Note: EasyData will launch automatically if the CBR 2™ motion detector is connected to a TI-84 Plus using a unit-to-CBR 2™ cable.

ÎTo set up the calculator for data collection:

a.Select Setup (press p) to open the Setup menu.

b.Press 2 to select 2: Time Graph to open the Time Graph Settings screen.

CBR 2 specifications

Texas Instruments has long been a prominent player in the field of educational technology, and the CBR 2 (Calculator-Based Ranger 2) is a testament to their commitment to enhancing the learning experience, particularly in the realms of mathematics and science. Designed to complement graphing calculators, the CBR 2 is a versatile data-collection device that empowers students and educators to explore real-world phenomena through hands-on experimentation.

One of the main features of the CBR 2 is its ability to capture a wide array of data through various sensors. The device is equipped with an array of built-in sensors that can measure motion, including speed and distance. This makes it an invaluable tool for physics experiments, allowing students to visualize concepts such as speed, acceleration, and trajectory.

The CBR 2 utilizes ultrasonic technology to detect distance through sound waves. This feature enables students to conduct experiments that demonstrate principles of sound and motion in a tangible way. With a range of up to 6 meters, the CBR 2 provides accurate and reliable measurements that can be graphically represented using compatible Texas Instruments graphing calculators.

The device is highly user-friendly, with simple interfaces that allow users to easily collect and analyze data. The integration with graphing calculators simplifies the process of data visualization, enabling students to create graphs in real time as they conduct experiments. This capability is particularly beneficial in encouraging interactive learning and fostering a deeper understanding of scientific principles.

The CBR 2 is designed to be portable and durable, making it suitable for classroom settings as well as outdoor experiments. Its compact size and lightweight construction ensure that it can be easily transported, allowing educators to take learning beyond the confines of the classroom.

The CBR 2 also supports various modes of data collection, including Event Mode, which allows users to trigger data collection based on specific events. This feature is useful in demonstrating concepts such as projectile motion and collisions, providing students with hands-on experience that enhances their learning.

In summary, Texas Instruments' CBR 2 is a powerful educational tool that enables students to collect, analyze, and visualize data in an engaging manner. With its built-in sensors, ultrasonic technology, and seamless integration with graphing calculators, the CBR 2 stands out as a versatile device that enriches the educational experience. It not only provides a platform for conducting experiments but also cultivates critical thinking skills and a deeper understanding of scientific concepts, preparing students for a future in STEM fields.
