Testing Constant Acceleration

On June 26, 2019, the DDL team tested the constant acceleration formulas by programming X1 to start with an initial velocity of v0 = 3 m/s and maintain a constant acceleration of a = 1 m/s2.  In the video, v is measuring the speed of the car while s is measuring the distance traveled. The red graph is a prediction of what the car will do while the blue graph is measuring what the car is actually doing.  The small difference between the graphs is due to an increasing drag force as the car accelerates.

Testing Full Power Acceleration

On June 26, 2019, the DDL team tested the full power acceleration of X1 by starting with an initial velocity of v0 = 3 m/s and giving the car full power for 24 seconds.  In the video, v is measuring the speed of the car while s is measuring the distance traveled. 

This test is part 2 of a 3 part test which includes:

Measuring Friction

On June 26, 2019, the DDL team tested friction at the Thunderhill skid pad.  X1 was programmed to drive in a circle with a constant radius of 20 m at increasing speed until the car lost traction and spun out (and we had a lot of fun while doing it!)

Braking Test

On June 26, 2019, the DDL team tested braking distances by taking Niki to the track at Thunderhill Raceway and measured the distance needed to stop from speeds of 15 mph, 30 mph, 45 mph, 60 mph, 75 mph and 90 mph.
