Constant Velocity Lab
By: Jake Williams & Lorenzo Aybar
Purpose:
The purpose is investigate the motion of a vehicle.
The purpose is investigate the motion of a vehicle.
Theory:
We used two methods to determine which one produces the better line or the more accurate line to find out the constant speed of the car.
First Method:
We measured out 10 feet as our distance knowing that one tile block equals 1 foot. Once the car started to accelerate, we timed the car using a stopwatch until the car crossed the 10 foot block. We then calculated the speed using this equation:
S=d/t
Second Method:
We measured out 10 feet as our distance knowing that one tile block equals 1 foot. Instead of using a stopwatch and a ruler, we used a motion sensor to measure out its speed and hopefully producing a more accurate constant speed once the car crosses the 10 foot line. We will then record and calculate the results on a position-time graph.

Experimental Technique:
To conduct this experiment, we built our car out of k-nex pieces including a battery-operated motor, ruler, stopwatch, and a motion sensor.
