A car ride

Accelerating objects - car

 

Objective:

In this experiment the objective is to study the motion of a car measuring its acceleration. The probe is an accelerometer connected to a CBL or a LabPro. Collected data will be stored in a graphing calculator and can be analysed either with the calculator or a computer, using previously collected data.

Nicholas Oresme, whose name is given in French as Nicole d' Oresme, was of Norman origin. He was born 1323 in Allemagne (France) and died in 1382 in Lisieux (France). Nothing is known of his early life, and the first that is known is that he studied for an Arts Degree in Paris in the early 1340s. Oresme invented a type of coordinate geometry before Descartes, finding the logical equivalence between tabulating values and graphing them in 'De configurationibus qualitatum et motuum'. He proposed the use of a graph for plotting a variable magnitude whose value depends on another variable. Oresme was the first to prove Merton's theorem, namely that the distance travelled in a fixed time by a body moving under uniform acceleration is the same as if the body moved at a uniform speed equal to its speed at the midpoint of the time period. 

Materials:

Car, CBL, accelerometer and a TI-83. Alternative procedure with stored data: just TI-83 or a PC with Excel.
