In this activity students collect distance-time data for different types of toy cars as they move away from the CBR2. Velocity and acceleration are also automatically calculated by the software.
It is interesting to compare the data for a car driven by an elastic band and for a spring-driven one. Students can identify the point at which motive power is lost and the vehicle begins to slow down.
There are more details about this activity in Capturing Data: Modelling and Interpretation, one of a series of booklets presenting STEM Activities with TI-Nspire, published by Texas Instruments in April 2010.
