The Ballistic Cart Accessory is an accessory for the Variable Speed Motorized Cart that shoots a plastic ball into the air that will then, if the cart is moving at a constant velocity, fall back into the catcher on the cart. It offers an interesting way of demonstrating projectile motion.

Mounted on a dynamics cart, the Ballistic Cart Accessory launches a ball vertically, continues down the track and then catches the ball as it falls- every time. Offers an exciting introductory demonstration to projectile motion.

An overview of PASCO Dynamics Systems and all the available systems, components and accessories.

Typical Applications

Features

PASCO's optical release does not affect cart motion or ball flight path.

The barrel has X and Y adjustments, so perfect vertical projections can be produced every time.

Fires a colored nylon ball 0.5 meters or higher - impressive for demonstration purposes.

The PASCO Ballistic Cart Accessory is used with a PASCO Dynamics Cart and track to shoot a plastic ball straight up from the moving cart. If the cart is moving at a constant velocity, the ball will fall back into the catcher on the cart. The ball is released using a photogate so there is no impulse given to the cart upon release as there is in other models relying on a string to release the ball. The barrel can be aimed to ensure that the ball is shot vertically. Special no bounce foam prevents the ball from bouncing back out of t he catcher cup.

Any of PASCO's dynamics systems, either Classic, PAScar or PAStrack. We highly recommend a longer track for this application. Use a 2.2 m Classic or PAScar System, or a 2.0 m or greater PAStrack length by connecting two or more track lengths.

Absorption Spectra

Lab Summary

Use a spectrometer to learn about the composition of the electromagnetic radiation in the visible range, to develop an understanding of how the interaction of objects and solutions with light result in the perception of color, and to dispel misconceptions of objects "having color."

A spectrometer is required to perform this lab. We recommend PASCO's Wireless Spectrometer.

Theory

This is used to ignite paper specifically. This works due to the quick compression, restricting the time for the heat to be exchanged between the air and its surroundings. The adiabatic compression reaches a temperature well above combustion. This tool serves as an introduction to how diesel engines work, as they also use adiabatic compression (burning fuel and not paper).
